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.


The new National Ocean Policy calls for actions to improve understanding of and capacity to respond to ocean acidification, recognizing the potential adverse impacts of an acidifying sea upon marine ecosystems. The effects of ocean acidification could significantly affect strategies for developing practices towards the sustainability of ocean resources. Basic research concerning the nature, extent and impact of ocean acidification on oceanic environments in the past, present and future is required. Research challenges include:

  • Understanding the geochemistry and biogeochemistry of ocean acidification;
  • Understanding how ocean acidification interacts with biological, chemical and physical processes at the organismal level, and how such interactions impact the structure and function of ecosystems, e.g. through life histories, adaptive evolution, food webs, biogeochemical cycling, and interactions with other changes in the ocean (e.g., temperature, stratification, circulation patterns); and
  • Understanding how the earth system history informs our understanding of the effects of ocean acidification on the present day and future ocean.

The Ocean Acidification program is in its fifth and anticipated last year of competition. We expect this to be the last solicitation specifically targeting Ocean Acidification.
