A grant from NSF

Life and Environments Through Time Grant

LET is an NSF research program supporting work on patterns and processes related to the origin and evolution of Earth’s climate, environments, life, and sedimentary record, from molecular to global scales and from the Archean through the Holocene. A strong fit is an eligible U.S.-based IHE or qualifying non-profit research or educational organization proposing research squarely within that deep-time scope. The packet does not supply formal review criteria, proposal-format requirements, award-size limits, or a deadline; applicants should consult NSF Publication 25-517 and the official notice before deciding to apply.

Plain-English explanation

Plain-English explanation

LET is an NSF research program supporting work on patterns and processes related to the origin and evolution of Earth’s climate, environments, life, and sedimentary record, from molecular to global scales and from the Archean through the Holocene. A strong fit is an eligible U.S.-based IHE or qualifying non-profit research or educational organization proposing research squarely within that deep-time scope. The packet does not supply formal review criteria, proposal-format requirements, award-size limits, or a deadline; applicants should consult NSF Publication 25-517 and the official notice before deciding to apply.

Editorial analysis

What the funder is trying to accomplish

NSF intends to support research that advances knowledge of patterns and processes relating to the origin and evolution of Earth’s climate, environments, life, and sedimentary record, at molecular through global scales and from the Archean Eon through the Holocene. The description also says this research can be useful for predicting and planning for future global change and for maintaining ecosystem services and human societies.

Editorial analysis

Strong-fit project signals

The research advances knowledge of patterns or processes related to the origin or evolution of Earth’s climate, environments, life, or sedimentary record. The work has a stated molecular, local, regional, or global scale and addresses a time interval within the Archean-to-Holocene range. The submitting organization is an eligible U.S.-campus IHE or an eligible U.S.-located non-profit, non-academic organization directly associated with educational or research activities. Where genuinely relevant, the proposal explains how the research could inform understanding of future global change, ecosystem services, or human societies. This is an inferred strategic strength rather than a stated review criterion.

Editorial analysis

What reviewers may prioritize

The packet provides no formal review criteria or reviewer guidance. Inferred priorities are a clear scientific contribution to knowledge of deep-time Earth systems, direct relevance to climate, environments, life, or the sedimentary record, and an explicit fit with the stated temporal and spatial scope. Potential relevance to future global change or ecosystem services may be useful context, but it is not documented as a review criterion.

What this grant funds

The Life and Environments Through Time (LET) program supports research that advances knowledge about the patterns and processes relating to the origin and evolution of Earth’s climate, environments, life, and sedimentary record. This research takes place at the molecular, local, regional, and global scales from the Archean Eon through the Holocene epoch. LET-supported research can be useful for predicting and planning for future global change, and for the maintenance and security of ecosystem services and human societies.
