Important information for proposers

All proposals must be submitted in accordance with the requirements specified in this funding opportunity and in the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. It is the responsibility of the proposer to ensure that the proposal meets these requirements. Submitting a proposal prior to a specified deadline does not negate this requirement.

Dear Colleague Letter

Supporting Open Polar Research Software

Invites the sustainable development and use of open source software, tools, libraries and frameworks that are critical for polar scientific objectives.

Dear Colleagues:

Federal agencies are celebrating 2023 as a Year of Open Science. Open software tools, libraries, frameworks, and data are playing increasingly prominent and impactful roles in activities supported by the Office of Polar Programs (OPP) in the Directorate for Geosciences (GEO), as they are across federally funded research. OPP published an updated Data, Code, and Sample Management Policy stating that “research software/code is identified as a research object and outcome that can also help make data more interoperable and reusable.” Documenting, sharing, and supporting open software/code are important parts of the polar research process which require both time and expertise, and support to achieve these goals should be included in NSF award budgets.

Complementing the disciplinary, interdisciplinary, and cyberinfrastructure goals articulated in the current Antarctic and Arctic solicitations, this Dear Colleague Letter (DCL) is designed to encourage the sustainable development and use of open source software, tools, libraries, and frameworks that are critical for OPP scientific objectives. OPP encourages submission of new proposals and supplemental funding requests which support the opening, documenting, and sharing of open polar research software/code. Proposed activities may include, but are not limited to:

  • Converting existing or legacy software/code into modern, open code to be released with an appropriate, open license;
  • Translating code from proprietary languages and/or environments into open languages and/or environments;
  • Upgrading, refining, and/or documenting experimental research software/code to enable broad use;
  • Organizing activities which advance the above goals through training, workshops, hackathons, cohort-building activities, etc.; and
  • Broadening participation and building open cyberinfrastructure skills and capacity in the polar research community across career stages and career paths.

Proposed activities should:

When making investments, OPP seeks broad representation of Principal Investigators (PIs) and institutions in its award portfolio, including a geographically diverse set of institutions (including those in EPSCoR jurisdictions) and PIs who are women, early-career researchers, members of underrepresented minorities, veterans, and persons with disabilities. PIs at all levels of software and cyberinfrastucture expertise are encouraged to consider submissions. Submissions which benefit and involve the full breadth of the polar research community, including undergraduates, graduate students, cyberinfrastructure professionals, and faculty at two-year and four-year institutions of higher education, including minority serving institutions and non-R1 institutions, are encouraged.

For more information on submitting proposals and supplemental funding requests, please consult the PAPPG. Proposals which align with this DCL can be submitted to the current Antarctic and Arctic solicitations, noting this DCL in the Project Summary. Principal Investigators are encouraged to contact Allen Pope, Program Officer for Polar Cyberinfrastructure (, with any questions pertaining to this DCL and to discuss the scope and size of potential proposals. For full consideration in Fiscal Year 2023, full proposals should be submitted by May 1, 2023 at the latest; supplemental funding requests may be submitted at any time.
