Opportunity Summary:
Funding Opportunity Number G13AS00019, titled "Cooperative Ecosystem Studies Unit, Gulf CESU," was a discretionary U.S. Geological Survey (USGS) funding opportunity administered by the USGS Alaska Science Center to support science and technology research and development through a cooperative agreement. The project focus was on developing precisely dated, year-by-year chronologies from lake trout otoliths (ear stones) and using those chronologies as indicators of lake productivity, then comparing the resulting fish-based records with existing dendrochronologies (tree-ring chronologies). Lake trout (Salvelinus namaycush) are emphasized because they are long-lived and non-migratory, traits that make them especially useful for reconstructing localized environmental and productivity histories over long time spans.
The core research objective was to produce "exactly dated" otolith chronologies, meaning the work was expected to go beyond general age estimation and instead build a dated time series that can be aligned to calendar years, similar in concept to how tree rings are dated in dendrochronology. By creating these otolith-based chronologies and comparing them to established tree-ring records, the project aimed to evaluate whether fish otolith growth patterns track broader environmental signals reflected in terrestrial proxies, and to assess how well otolith-derived information can serve as a complementary record of aquatic ecosystem productivity. In practical terms, this kind of study can help link changes in lake conditions to climate variability and other drivers, using a biological archive preserved within fish hard parts.
The award mechanism was a cooperative agreement, which typically indicates substantial involvement or collaboration with the federal agency during the project, such as joint planning, coordination, or technical participation by USGS staff. The opportunity anticipated a single award (ExpectedAwards: 1) with an estimated total funding amount of $112,986. No cost sharing or matching was required. The listing referenced CFDA number 15.808 (U.S. Geological Survey Research and Data Collection), situating the work within USGS research and data collection activities.
Eligibility was restricted to organizations that are participating partners of the Pacific Northwest Cooperative Ecosystem Studies Unit (CESU) Program, reflecting the CESU structure as a network of partnerships designed to provide research, technical assistance, and education services supporting public trust resource stewardship. The solicitation was posted on January 8, 2013, with an original and current closing date of January 18, 2013, and it was archived on March 8, 2013.

What does a cooperative agreement imply for this opportunity?
Based on the description provided, a cooperative agreement typically indicates substantial involvement or collaboration with the federal agency during the project, such as joint planning, coordination, or technical participation by USGS staff.
What was the overall purpose of the project?
The project supported science and technology research and development focused on developing precisely dated, year-by-year chronologies from lake trout otoliths (ear stones) and using those chronologies as indicators of lake productivity, then comparing those fish-based records to existing dendrochronologies (tree-ring chronologies).
What are otoliths, in the context of this opportunity?
In this opportunity, otoliths are described as lake trout "ear stones" used to develop year-by-year growth chronologies.
What species was emphasized in the project and why?
The project emphasized lake trout (Salvelinus namaycush) because they are long-lived and non-migratory, traits described as especially useful for reconstructing localized environmental and productivity histories over long time spans.
What does "exactly dated" otolith chronology mean here?
"Exactly dated" means the work was expected to go beyond general age estimation and instead build a dated time series that can be aligned to calendar years, similar in concept to how tree rings are dated in dendrochronology.
What was the core research objective?
The core objective was to produce exactly dated otolith chronologies and compare them to established tree-ring records to evaluate whether fish otolith growth patterns track broader environmental signals reflected in terrestrial proxies, and to assess how well otolith-derived information can serve as a complementary record of aquatic ecosystem productivity.
What environmental or ecosystem insights was the study intended to support?
The description indicates this kind of study can help link changes in lake conditions to climate variability and other drivers by using a biological archive preserved within fish hard parts.
How were dendrochronologies (tree-ring chronologies) used in the project?
Existing dendrochronologies were intended to serve as comparison records for the fish otolith chronologies, to test alignment of environmental signals between aquatic (otolith) and terrestrial (tree-ring) proxies.
How many awards were anticipated?
The opportunity anticipated a single award (ExpectedAwards: 1).
What was the estimated total funding amount?
The estimated total funding amount was $112,986.
