Background: PIFSC seeks to procure two sets of ecosystem sensors- a dissolved oxygen sensor (Aanderaa 4831 optode) or equivalent The Pacific Islands Fisheries Science Center (PIFSC) has recently invested in a Seaglider uncrewed profiling glider systems to support ecosystem survey operations. Autonomous oceanographic sampling platforms can increase the temporal and geographic scope of critical ecosystem sampling operations that are required to characterize and monitor the pelagic ecosystem.

Critical sensor systems- optical and dissolved oxygen- were not procured with the Seaglider vehicles and are needed to maximize sampling of critical ecosystem components. Assessment of chlorophyll-a fluorescence, dissolved organic matter concentration, backscatter, and dissolved oxygen concentrations will allow us to further constrain estimates of the distribution and composition of pelagic communities and support ecosystem model assessment and parameterization.

Continued testing and near-term operations require critical supplies. PIFSC provides scientific information for conserving and managing U. S. and world fisheries, populations of protected marine species, and their habitats. Research is conducted to estimate the biological, environmental, and economic impacts of different fisheries management options, and advice is given to domestic and international organizations that manage living marine resources.

In comparison to many coastal marine habitats, the pelagic realm of the tropical and subtropical oceans appears featureless and homogenous. However, the communities of animals in this ecosystem are structured by physical and biogeochemical differences in water masses (vertically, horizontally, and temporally) that have a strong influence on spatial distribution and interspecific interactions.

Dissolved oxygen concentrations, particle concentration, and fluorescence are key water column properties that shape the structure of marine ecosystems. Acquiring appropriate sensors for estimating these properties in the upper 2000 m of the water column will increase the utility of SGX platforms on which they are deployed, and this procurement action supports PIFSCs continued investments and pivot toward uncrewed vehicles to carry out pelagic ecosystem sampling operations.
