Walter Sullivan Award for Excellence in Science Journalism – Features

Walter Sullivan Award for Excellence in Science Journalism – Features

The Walter Sullivan Award for Excellence in Science Journalism – Features is an annual American Geophysical Union (AGU) honor for feature journalism about the Earth and space sciences. AGU gives the award to an individual journalist or a group of journalists whose feature story or series makes scientific information accessible and interesting to non-scientists without sacrificing accuracy.

This page is a historical reference for the 2026 award cycle. AGU’s journalism portal stated that nominations for the 2026 awards were accepted through April 19, 2026. That window is closed. AGU’s official award page does not publish a 2027 nomination deadline, so this entry does not present a future date or a live application route. Check the official AGU award page for any later announcement before preparing a new nomination.

The award remains useful to understand even while a cycle is closed. It identifies the kind of journalism AGU values, the people who can be nominated, the boundaries around eligible work, and the practical materials that mattered in the closed 2026 process. Those details can help a journalist or editor decide whether a future feature is a sensible candidate, but they should not be treated as confirmation that submissions are open now.

At a Glance

Status of the 2026 Cycle

The 2026 cycle is finished. AGU’s journalism-awards portal identified April 19, 2026 as the closing date and said that the 2026 awards honored stories first published during 2025. The portal also described the Walter Sullivan Award as the Features award, distinguishing it from the David Perlman Award for news reporting. Because the deadline has passed, there is no current 2026 submission action to take from this page.

The closed-cycle date is retained in the metadata as 2026-04-19 so the archive record has a precise, verifiable date. The historicalReference flag marks that date as belonging to a completed round. It is not a suggested 2027 deadline, and it should not be used to plan a new nomination. No 2027 date has been added because AGU has not published one on the official award page checked for this update.

For the same reason, the official URL in this record now points to AGU’s award explainer rather than the old login or solicitation address. A login page can be useful when a nomination window is open, but it is a poor permanent reference after the portal closes. The AGU award page is the stable place to confirm the award’s purpose, eligibility, benefits, and any future instructions.

Why This Science Journalism Prize Matters

The award’s distinctive value comes from the combination of scientific subject matter and public-facing storytelling. AGU asks whether a feature brings important information or concepts about AGU sciences to the public, corrects misconceptions, or makes the science accessible and interesting to a general audience. The criteria also name accuracy, initiative, originality, and clarity.

That combination gives the award a clear editorial center. A story is not a strong candidate merely because it discusses climate, geology, oceans, planetary science, earthquakes, weather, or another compelling subject. The reporting and writing have to help a non-specialist understand why the science matters. A technically correct piece that assumes specialist knowledge may miss the communication goal. A dramatic piece that bends evidence may miss the accuracy requirement.

Feature journalism is also central. AGU’s award page describes the work as prepared with a deadline of more than one week. That points toward reporting that has time for sourcing, context, explanation, and deliberate structure. A story about groundwater, a changing coastline, a satellite mission, wildfire smoke, a fault system, or a planetary discovery could fit the subject area, but the topic alone does not establish eligibility. The finished work must meet AGU’s journalism and audience standards.

What This Opportunity Offers Beyond the 5000 Dollar Prize

The award carries a $5,000 prize. AGU also lists an engraved award, recognition in Eos, recognition at the annual meeting in the year the honor is awarded, travel expenses of up to $1,000 to attend that meeting, and two tickets per winner to the Honors Banquet. These are benefits for recipients, not guaranteed support for nominees.

The travel provision has a specific condition: AGU describes it as travel to the annual meeting in the year the honor is awarded. It should therefore not be read as an automatic reporting grant or as a general reimbursement available during the nomination process. A journalist considering a future nomination should consult the current AGU page for any changes to the benefits or event details.

Who Should Apply for This Journalism Award

AGU’s eligibility rules are specific but broad in format. The nominee must be a journalist working in any medium except books. A nominee may be a sole author or part of a team of up to four contributors, including contributors to audio or visual components. The author may work for a print or electronic publication, a broadcast or cable station or network, or as a freelancer.

AGU membership is not required for nominees or nominators. Self-nominations are permitted, and another person may nominate a story or journalist. Nominations may come from any country and in any language, provided an English translation is supplied when needed. The work must be focused on one or more scientific disciplines represented by AGU and published in an editorially independent journalistic outlet.

There are meaningful exclusions. Books are not eligible. AGU says stories published in Eos are not eligible, opinion pieces are ineligible, and the organization does not currently offer an award for institutional science writing. A nominee may submit only one entry for the Sullivan Award in a given year. AGU also excludes nominees who won the Sullivan Award during the past two award cycles from the current award cycle.

For the 2026 cycle, eligible entries had to be first published between January 1 and December 31, 2025, intended for and available to the general public. That publication window belonged to the closed 2026 award and should not be assumed for a future year until AGU publishes updated instructions.

What Kind of Work Fits Best

The best fit is a feature story or series that connects reliable Earth or space science with a public audience. AGU’s examples of the award’s purpose include bringing timely concepts to public attention, correcting misconceptions, and explaining science without losing accuracy. A narrative investigation, explanatory feature, long-form broadcast piece, or text-centered multimedia project may be relevant if it satisfies the published rules.

The feature distinction separates this honor from a breaking-news category. AGU describes Sullivan work as generally produced under a deadline longer than one week. That does not create a promise that every long project will qualify. It does, however, signal that the judges are assessing reporting and writing with room for depth, initiative, originality, and clear explanation.

Series work has its own limit. For the 2026 instructions, nominators could submit up to three parts of a multi-part series, or selected parts, and the committee would evaluate them together as one submission. A journalist planning a future entry should confirm whether that limit and the treatment of series remain unchanged.

Materials and Submission Instructions From the Closed 2026 Cycle

Because the 2026 nomination window is closed, these are archive notes rather than instructions to submit today. AGU’s portal said submissions should be text-based. It instructed nominees to upload anonymized PDFs with identifying information or features removed, including names, outlets, links, and identifiable fonts, while placing the story headline at the top of each page. The purpose was blind judging, and AGU warned that failure to follow the upload instructions could make a submission ineligible.

For online-only elements, the 2026 portal allowed a link to the web version at the top of the entry while asking nominees to hide the outlet within the text. If the entry included audio or video, an anonymized transcript was required, with host, producer, and outlet names redacted while scientist and guest names could remain. If a photographer or illustrator was not nominated, the relevant photos or graphics were to be excluded from the PDF. If those creators were nominated, the submission could include the images and captions without credit lines.

The 2026 portal also said that entries in a language other than English needed an anonymized translation and that no letter of support was needed. It reported no fee for nominating one’s own or another person’s work. These details are useful when assessing the effort involved, but a future round may change them. Confirm the live requirements on AGU’s official page before assembling files.

What Makes an Application Stand Out to Judges

The official criteria provide a useful checklist for editorial review. Accuracy matters first: claims, numbers, quotations, and explanations should survive scrutiny. Clarity matters because the target audience is not limited to specialists. Initiative and originality matter because the judges are looking for journalism that does more than repeat a familiar release or restate a paper. The story should have a reason to exist and a reporting approach that gives readers something they could not get from a summary.

Audience connection should come from the reporting rather than from inflated language. A feature can make a scientific process understandable through people, places, evidence, consequences, and careful explanation. It can show why a measurement matters, how a field team handles uncertainty, or how a technical finding changes the way a community understands a risk. The subject can be complex; the reader should not have to be a specialist to follow the central argument.

A prospective nominee should also make the work easy for judges to assess. The 2026 rules emphasized anonymization, clean text, accessible files, and accurate handling of multimedia contributors. Those are administrative details, but they protect the work from being weakened by avoidable confusion.

How to Handle a Future Cycle

There is no live application step for the archived 2026 round. When AGU announces a later cycle, begin by reading the current award page and the linked nomination instructions. Confirm the award year, the eligible publication period, the deadline, whether the work must be text-based, the treatment of series and multimedia, and the anonymization rules. Do not rely on the 2026 deadline or assume that an old portal link has reopened.

Then select one eligible work. Check that it is a feature rather than a book, opinion piece, institutional science-writing project, or a story published in Eos. Confirm that it was published in an editorially independent outlet, addresses an AGU scientific discipline, and was available to the general public. If the work is collaborative, identify no more than four nominated contributors and explain each person’s role accurately.

Finally, prepare the entry files in the format AGU specifies for that round. Build in time to remove names, outlet clues, links, and other identifiers if blind judging is required. Test any approved web links, prepare transcripts or translations where required, and review the submission against the current instructions before sending it. The correct next action is to monitor AGU’s official page until a new cycle is actually announced.

Common Mistakes to Avoid

The most serious mistake now would be treating an archive page as an open form. The 2026 date has passed, and this record does not provide a current submission CTA. A second mistake would be inventing a 2027 deadline from the fact that AGU describes the award as annual. Annual awards can change their dates, publication windows, or instructions; only an official announcement establishes the next round.

For a future cycle, avoid selecting a story solely because the topic sounds important. AGU evaluates the journalism: reporting, writing, accuracy, initiative, originality, clarity, and accessibility to general audiences. Avoid specialist language that the story never explains, unsupported claims that overstate the science, and a narrative that hides the evidence under decoration.

Also avoid administrative oversights. A team entry should name the people whose work is being judged. A multimedia entry should follow the current rules for including or excluding creators and files. Anonymized PDFs should actually be anonymized. Publication dates should be checked against the announced eligibility window. These checks are especially important when a story is assembled from text, graphics, audio, video, or translated material.

Frequently Asked Questions

AGU’s published eligibility includes freelance journalists, along with authors employed by print or electronic publications and broadcast or cable stations or networks. Confirm the current wording when a new cycle opens.

Do I need to be a member of AGU?

No. AGU says membership is not required for nominees or nominators.

Can I nominate myself?

Yes. Self-nominations are permitted under AGU’s published rules. A person may also nominate another journalist or story.

Can a team submit one project together?

Yes. The award allows a sole author or a team of up to four contributors, including contributors to audio or visual components. The 2026 portal also required that the relevant multimedia creators be included when those elements were part of the entry.

Are books eligible?

No. The award covers feature stories or series in any medium except books.

Can I submit more than one story?

AGU’s rules allow only one entry for the Sullivan Award in a given year. The 2026 portal allowed up to three parts of a multi-part series to be submitted together, subject to its instructions.

If I won recently, can I enter again?

AGU says nominees who won the Sullivan Award during the past two award cycles are not eligible for the current cycle.

Does the work have to be about all science?

What to Remember

The Walter Sullivan Award is a strong fit for journalism that joins careful Earth and space science reporting with accessible feature storytelling. Its published benefits include a $5,000 prize and recognition connected with AGU, while its criteria emphasize accuracy, initiative, originality, clarity, and public understanding.

For now, the practical conclusion is simple: the 2026 round is closed, the retained deadline is April 19, 2026, and no 2027 date is confirmed here. Use AGU’s official award page as the source of truth for a future nomination cycle. When a new announcement appears, refresh the year, deadline, publication window, and submission instructions before treating the opportunity as current.

How to Apply

There is no current application CTA because the 2026 nomination window has closed and AGU has not published a 2027 deadline on the official award page checked for this update. For the award description, eligibility rules, benefits, and any future nomination announcement, use the official Walter Sullivan Award page. Do not use the former solicitation login URL as evidence that nominations are open.
