Iceland Ocean Climate Science Joint Learning Opportunity (Historical Reference)

Iceland Ocean Climate Science Joint Learning Opportunity — Historical Reference

Overview

This page is a historical reference for the Iceland Ocean Climate Science Joint Learning Opportunity (JLO), a 2025 research call run by the Carbon to Sea Initiative with Röst Marine Research Center. The call supported additional scientific, technical, and social research alongside planned ocean alkalinity enhancement (OAE) field research in Hvalfjörður, Iceland. The official program page records the extended application deadline as March 24, 2025, and the RFP set the submission time at 5:00 PM GMT. That cycle is closed.

This is an archive, not a live application listing. Carbon to Sea’s official Iceland JLO page still describes the 2025 call and provides the 2025 RFP documents; I found no newer Iceland-specific JLO announcement there. Carbon to Sea’s 2025 annual report says it continued supporting Röst and reports that Röst completed a hydrodynamic field study in Hvalfjörður in October with [C]Worthy and the University of Iceland. The report describes a hydrodynamic study; it should not be mistaken for confirmation that every proposed JLO activity or the planned alkalinity addition occurred. Röst’s current research page says a small-scale OAE field study is planned for October 2026. Icelandic authorities have granted the research permit subject to detailed conditions and oversight, and Röst says the plan was adjusted in response to local feedback. That is ongoing site research, not a new JLO or an open application route for outside teams. Separately, Carbon to Sea’s 2026 call page describes two broad OAE funding opportunities: a Global OAE Field Research Network with up to $5 million in total awards and a Targeted Research & Innovation call with up to $1 million. The published pre-proposal deadline was September 30, 2026, and the page says that submission window has passed. The same call page gives December 15, 2026 as the full-proposal deadline for applicants invited to stage two. Those calls do not renew the Iceland JLO. Anyone invited to stage two should confirm instructions directly with Carbon to Sea rather than treating this archive as an application route.

OAE research is not a conventional startup grant or a permit to deploy material in the ocean. It is concerned with whether raising seawater alkalinity can remove atmospheric carbon dioxide, how that effect can be measured, and what ecological and social effects may occur. The opportunity was designed for work that adds evidence to a closely monitored field program, not for an unsupported commercial claim or a request for carbon-credit revenue.

At a glance

What the Iceland work appears to offer

The 2025 JLO was an add-on research opportunity around a planned field program, not a general cash award for an ocean startup. Carbon to Sea and Röst described Hvalfjörður as a research setting selected after Carbon to Sea and Transition Labs evaluated 14 possible locations using criteria that included sensitive habitats, zoning conflicts, port access, baseline data, and local interest.

The setting was built around evidence collection. The 2025 RFP described a fluorescent dye study planned for May and a small-scale OAE pilot tentatively planned for September 2025. Those were plans at the time of the call, and the RFP said dates could change with regulatory feedback, weather, or other conditions. Carbon to Sea’s 2025 annual report later records a hydrodynamic field study completed in Hvalfjörður in October, intended to track dispersion and examine the site’s scientific potential. The report describes that work as a hydrodynamic study; it should not be mistaken for confirmation that every proposed JLO activity or the planned alkalinity addition occurred. The wider site program also built on regional ocean modeling, baseline measurements of physical, biogeochemical, pelagic, and benthic conditions, a dual-tracer release study, site evaluation, regulatory work, and community engagement. The JLO aimed to support research into seawater chemistry, carbon dioxide measurements, dispersion, and marine ecosystems.

For a qualified team, the award package could include research funding, Röst meeting or working space, operational and logistical assistance, access to an alkalinity dosing data package, and in-kind support. The RFP did not promise the same package to every awardee; it said the award would reflect the needs of the proposed work. The total budget was a program ceiling shared among successful applicants, not a guaranteed amount per project.

Do not read the JLO as an automatic permit, a commercial demonstration license, or a guarantee that a proposed experiment would take place. The original RFP set readiness around the May and July 2025 research dates; the later JLO Q&A says the alkalinity release had been rescheduled to September. The RFP and Q&A both cautioned that field dates could change because of regulatory direction, weather, or other unforeseen circumstances. The program is now historical, so any new work must be discussed through the current Carbon to Sea and Röst channels.

What ocean alkalinity enhancement means here

Ocean alkalinity enhancement is a proposed carbon dioxide removal pathway. The basic idea is to increase the alkalinity of seawater so the ocean can take up more CO2 from the air and store it in dissolved inorganic carbon forms for long periods. There are multiple technical pathways, including mineral-based approaches and electrochemical or engineered systems. Carbon to Sea says it is pathway-agnostic and interested in whether OAE can be safe, effective, durable, scalable, and measurable.

For applicants, this means the proposal needs to be framed as a research question, not a sales pitch. A strong concept should say what alkalinity pathway is being tested, what chemical or physical signal should appear, how that signal will be measured against background ocean variability, and what ecological effects could occur. The proposal should also explain what would count as a negative result. Funders that work in this area generally respect uncertainty when it is handled openly. They are less likely to trust claims that imply guaranteed carbon removal before field evidence exists.

This page should not be read as support for unrelated marine carbon-removal methods. The earlier metadata referenced kelp cultivation and biochar sinking, but the official Carbon to Sea pages checked for this rewrite focus on OAE. If your work is seaweed sinking, wood sinking, ocean biomass sinking, or marine biochar disposal, verify directly before assuming it fits. You may need a different funder, a different permit path, and a much stronger environmental justification.

Who should consider pursuing it

For the archived Iceland JLO, the RFP sought research teams that could add value to planned Iceland field work. It welcomed international proposals and asked applicants to be affiliated with an established, legally recognized organization or research institution able to receive charitable donations. That rule belongs to the closed 2025 cycle. The separate 2026 Carbon to Sea guidance says the lead applicant must be formally affiliated with an eligible entity, such as a research organization, academic institution, incorporated company, or nonprofit. The entity must be legally recognized, able to receive charitable donations, and able to conduct research, technology development, technical analysis, network-building, or stakeholder engagement. The 2026 guidance states there are no geographic restrictions and allows multi-institution proposals if the lead organization can receive the full award and make sub-grants as needed.

The strongest proposals would have shown scientific merit, strategic fit, a clear and practical execution plan, appropriate qualifications, technical feasibility, and cost-effectiveness. The work could address biological impact monitoring, synthesis of biological responses, sensor deployment for measurement, reporting and verification (MRV), uncrewed surface-vessel data tools, modeling, public-sentiment research, or community engagement. Projects needed to add knowledge beyond the existing field-research activities rather than duplicate them without a clear reason.

The JLO was a weak fit for a team whose main objective was to sell carbon credits, avoid public scrutiny, or conduct a large deployment before safety and measurement questions were addressed. It was also not a generic climate-technology subsidy. A proposal needed to explain the research question, the measurement approach, the relationship to the planned field work, and the public or scientific value of the results.

Eligibility and fit checklist

The official 2025 RFP provides the following eligibility screen. It is useful for understanding the closed cycle, but it should not be treated as the eligibility rulebook for the newer global RFP.

If you cannot answer most of these questions yet, spend more time on project design before approaching Carbon to Sea. A short, precise concept note will be more credible than a long proposal that hides weak assumptions.

Application process

The Iceland JLO submission route is closed. For the archived cycle, applicants used the Proposal Application Guidelines and emailed their submission to the JLO Management Team at [email protected] by March 24, 2025 at 5:00 PM GMT. That address and deadline should not be used for a new project.

The distinct 2026 Carbon to Sea research call required a short pre-proposal through its online submission form. The pre-proposal limit was 1,750 words, with a project summary, desired outcomes, technical approach, potential site, team and partners, readiness, risks, approximate funding request, and budget justification. For Network Participation grants, a simplified set of questions applied. Supplemental materials such as references and short team bios were allowed. Only applicants selected at stage one could submit a full proposal, which undergoes scientific peer review. The public pre-proposal deadline of September 30, 2026 has passed. Carbon to Sea’s page lists December 15, 2026 as the full-proposal deadline; that stage is invitation-only. Anyone already invited should use the official guidance and contact [email protected] for current submission instructions. This broader call does not renew the Iceland JLO or guarantee that Hvalfjörður proposals will be selected.

Timeline and deadline

The deadline for this specific JLO was March 24, 2025 at 5:00 PM GMT. The original deadline was March 10, 2025, and the official RFP records March 24, 2025 as the extended proposal deadline. Applications are closed, so the date remains in the metadata only as the real closing date for the archived cycle. historicalReference = true tells the site not to present it as a live opportunity.

The RFP described research activity planned for May and September 2025 and warned that dates and details could change because of regulatory feedback, weather, and other factors. Those plans describe the closed JLO and are not a current promise of field access.

The later 2026 call is distinct from the Iceland JLO. Its two parts cover field-site exploration, development, field research and network participation, plus targeted research on sediment additionality and alkalinity innovation. Carbon to Sea lists up to $5 million total for the field network and up to $1 million total for targeted research. These are portfolio ceilings, not individual award promises. The public pre-proposal deadline has passed; the full-proposal stage is limited to invited applicants. A project in Iceland would need to meet the relevant current call scope and compete through that process; the old JLO’s eligibility, amount, and email route do not carry over.

If you are trying to run a field activity in a particular season, start early. Icelandic marine work is affected by weather, vessel availability, sampling windows, equipment shipping, customs, permits, and local operating constraints. A proposal that assumes perfect timing will look fragile.

Materials to prepare

A strong first package should be concise but technically serious. Prepare these materials before you ask for a call:

• A one-page project summary written for an informed non-specialist.
• A technical memo describing the OAE pathway, expected signal, and key uncertainties.
• A field-readiness note explaining why the question needs a real-world Iceland site.
• A monitoring plan covering water chemistry, physical oceanography, biology, and quality control.
• A modeling or data-analysis plan explaining how you will interpret results.
• An environmental-risk memo with clear pause, modify, and stop conditions.
• A partner list showing who is responsible for science, operations, data, permits, safety, and communication.
• A draft budget that separates personnel, equipment, vessels, sampling, lab analysis, modeling, community engagement, and contingency.
• A publication and data-sharing plan.

The most important document is usually not the budget. It is the monitoring and learning plan. Marine carbon removal claims can be undermined quickly if the team cannot show what happened in the water, what was expected, what changed, and how uncertainty was handled.

Selection and readiness tips

Write for mixed reviewers. A marine chemist, an engineer, a local operator, a community representative, and a funder may all read the same material. Use plain English first, then put technical depth in annexes. If the proposal cannot be understood without jargon, it is not ready.

Be specific about scale. Say whether you are asking for modeling support, instrument deployment, a small in-water tracer study, a controlled alkalinity addition, a sensor validation exercise, or a longer monitoring campaign. “Pilot” is too vague by itself.

Show how your work uses the Iceland site rather than merely occurring there. Hvalfjordur is described by Carbon to Sea as useful because of its fjord setting, cold water, wind, shelter, port access, baseline-data considerations, and local research structure. Explain which of those features is relevant to your question.

Treat ecological monitoring as core work. Do not place it in a short appendix after the carbon-removal claim. Reviewers will want to know what organisms, habitats, fisheries, or sensitive areas could be affected and how you would detect problems.

Make uncertainty visible. Include expected ranges, detection limits, model assumptions, confounding factors, and reasons the work might fail. A funder that says it is outcome-agnostic should not be asked to accept overconfident claims.

Separate research outputs from commercial outputs. It is fine to explain how the work could later support scale-up, but the immediate value should be credible evidence: datasets, model validation, environmental-impact findings, instrument performance, protocol improvement, or policy-relevant learning.

Common mistakes

One common mistake is treating the official page as if it were a standard grant form. It is not. If you send a full proposal without confirming fit, you may waste time and create a poor first impression. Start with a focused concept and a clear question.

Another mistake is using the wrong source. The Carbfix homepage is not the right application page for this marine OAE opportunity. Similarly, an Icelandic public climate fund may be relevant for some climate projects, but it is not automatically the same as Carbon to Sea’s Iceland field-research program. Match the source to the project.

A third mistake is making carbon-removal claims before measurement is credible. In OAE, the central challenge is not only adding alkalinity. It is proving what happened after addition, how the ocean responded, whether CO2 uptake occurred, how long the effect lasts, and whether environmental side effects are acceptable.

A fourth mistake is ignoring local legitimacy. Hvalfjordur is a real place, not just a coordinate on a map. Local leadership, community engagement, port logistics, fisheries considerations, and Icelandic regulatory expectations all matter. A proposal that treats local issues as administrative cleanup will look weak.

A fifth mistake is proposing a field trial too soon. If the lab chemistry is unclear, the sensor package is untested, the model cannot resolve the expected signal, or the ecological-risk analysis is thin, the better request may be for preparatory research rather than in-water activity.

FAQ

Is this currently open for applications?

No Iceland-specific JLO is open, and no replacement Iceland JLO has been announced on the official program page checked for this update. Röst separately lists an OAE field study planned for October 2026 under a permit granted subject to detailed conditions and oversight; that site research is not an application round. The separate 2026 Carbon to Sea calls closed pre-proposals on September 30, 2026. Only invited applicants can proceed to the full-proposal stage, whose published deadline is December 15, 2026.

What was the award amount?

The 2025 RFP allocated up to $300,000 to the JLO in total, divided among winning awardees. It also described possible in-kind logistics, workspace, operational assistance, and access to dosing data. It did not promise $300,000 to each winner.

Is Carbon to Sea the only organization involved?

No. Carbon to Sea provided funding and strategic R&D alignment, while Röst Marine Research Center led the Iceland JLO’s administration, site leadership, and operational support. The RFP also described research contributions from [C]Worthy, GEOMAR, Ghent University, the University of Iceland, and other partners.

Could a startup apply?

The 2025 eligibility text focused on individuals or teams affiliated with established organizations or research institutions capable of receiving charitable donations. A commercial organization would have needed to fit that requirement and demonstrate relevant research capacity; a commercial pitch without a strong research design was not enough.

Could international teams participate?

Yes, the 2025 RFP expressly said international proposals were welcome. They still needed an eligible organizational affiliation, relevant experience, the ability to work in Iceland during the required period, and a credible plan for coordination with Röst and the wider research team.

Did the award replace permits?

No. The RFP described operational assistance and permits as possible parts of the JLO support, but funding did not remove the need for regulatory direction, site approval, safety planning, environmental review, or local coordination.

What if my project is not OAE research?

Do not assume fit. The official Iceland JLO documents focus on OAE field research and closely related monitoring, modeling, environmental, technical, and social questions. A different marine carbon-removal method would need separate confirmation from the current funder.

What to do next

This Iceland-specific opportunity is closed. Do not send a proposal to the archived JLO email address or treat March 24, 2025 as a current deadline. Carbon to Sea’s separate 2026 call is also past its public pre-proposal deadline. If you submitted a pre-proposal and received an invitation, follow the official stage-two instructions and confirm the December 15, 2026 deadline and requirements with Carbon to Sea. If you did not apply, monitor the official call pages for future rounds; do not assume one is scheduled or that the Iceland JLO will return.

For a future call, first match the project to the published grant type. A field-site proposal should explain the site’s scientific value, current infrastructure and baseline data, local partnerships, permitting path, and capacity for sustained research. A targeted research proposal should answer a focused technical or scientific question in one of the announced priority areas. Build a clear measurement and risk plan, document the lead applicant’s institutional capacity, identify collaborators and sub-grant arrangements, and develop a realistic budget. Review that round’s application guidance and terms before submitting; the 2026 forms and rules may not apply to later rounds.

The 2025 JLO was a defined, time-limited call with a real deadline, a shared $300,000 budget ceiling, specific eligibility rules, and a direct email submission route. It remains useful as a record of how Carbon to Sea and Röst invited outside research partners to the Hvalfjörður work. The 2026 global calls represent a separate program design, with different eligibility, budgets, subjects, forms, and review stages. Treat each official call document as controlling for its own round, and rely on a later Carbon to Sea notice before presenting any future Iceland funding as available.
