Important information about NSF’s implementation of the revised 2 CFR

NSF Financial Assistance awards (grants and cooperative agreements) made on or after October 1, 2024, will be subject to the applicable set of award conditions, dated October 1, 2024, available on the NSF website. These terms and conditions are consistent with the revised guidance specified in the OMB Guidance for Federal Financial Assistance published in the Federal Register on April 22, 2024.

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

Seafloor Geodesy

Invites proposals for field campaigns to deploy seafloor transponders from the existing instrument pool for four sites at tectonic settings in the Cascadia and Alaskan subduction zones.
Invites proposals for field campaigns to deploy seafloor transponders from the existing instrument pool for four sites at tectonic settings in the Cascadia and Alaskan subduction zones.

Dear Colleague:

NSF recognizes the unique contribution of offshore geodetic measurements and recently funded the construction of 48 seafloor geodetic transponders, their benchmarks, and 3 wave gliders. A community workshop and report https://www.seafloorgeodesy.org/post/future-directions-in-seafloor-geodesy-2021-community-workshop highlighted several recommendations for the application of seafloor geodetic techniques to constraining offshore geodetic measurements in different environments. A follow-on community workshop https://www.seafloorgeodesy.org/post/workshop-on-the-alaska-and-cascadia-seafloor-geodetic-community-experiment discussed the design of a community experiment to deploy a subset of this instrument pool in the Cascadia and Alaskan subduction zones.

The subduction community experiment will only use a subset of the instruments available which leaves enough instruments to address other science needs. Considering this, NSF invites proposals for field campaigns to deploy seafloor transponders from the existing instrument pool for 4 sites at tectonic settings consistent with priorities identified in the 2021 Community Workshop report. The geodetic instruments have a depth limit of 3000 m. A multi-year deployment is envisioned with requisite waveglider surveys. Of particular interest are proposals that target volcanic processes, transform processes, plate motions, or polar regions.

PROPOSAL PREPARATION AND SUBMISSION

Projects can be PI-driven or Community-driven. Proposers should contact program officers Gail Christeson gchriste@nsf.gov or Michael Jackson mejackso@nsf.gov early in the proposal development process for seafloor geodetic facility budget preparation guidance. Proposals should be submitted by February 15, 2024, for full consideration.

TO WHAT PROGRAM SHOULD I SUBMIT MY PROPOSAL?

While additional funds may be provided by other programs as appropriate, interested parties should plan to submit all proposals for deployment of these seafloor geodetic instruments to the Marine Geology and Geophysics Program (MG&G).

PEER REVIEW AND FUNDING

Proposals will be reviewed with and compete for funding with other proposals submitted to the MG&G Program. As such, the total budget should be commensurate with the proposed scope of activities.

Sincerely,

Alexandra R. Isern
Assistant Director
Directorate for Geoscience
