Evaluating injury and mortality to larval lamprey collected out of sediment using a portable suction dredge

Dataset describes the findings of a combination of field and laboratory tests to see if larval lamprey were injured or killed after they were collected from their burrows in sediment using a portable suction dredge.

Data collected in 2010 to evaluate habitat availability for surf smelt and eelgrass in response to sea level rise on Bainbridge Island, Puget Sound, Washington, USA

This dataset includes biological variables showing surf smelt spawning presence, geological variables describing beach composition, and sample locations using RTK-GPS. This field data was also used to run the Sea Level Affecting Marshes Model (SLAMM; Warren Pinnacle Consulting, Inc., Warren, Vt)) to predict the changes to beaches over time, and under different sea level rise scenarios. Field sampling took place on the northern part of Bainbridge Island, Puget Sound, Washington during summer and fall of 2010.

Counts, Fish Weights, and Spectral Data from a Juvenile Chinook Salmon Polyester Microplastic Fiber Exposure Study

This release includes all data collected in support of a juvenile Chinook salmon exposure study designed to understand the retention of microplastic clothing fibers (hereon refered to as "microfibers") after feeding. To understand the potential impacts of microfiber ingestion to fish, we ran a feeding experiment with juvenile Chinook salmon to determine if ingested fibers are retained and/or digestion rates altered over a full, experimentally determined, 10 day digestion period. Data includes: fish weights, microfiber counts, and quality assurance (QA) data for the experiment. QA steps are detailed in the process section of the metadata.

Maternal transfer of PCBs in Pacific sand lance in Puget Sound, Washington

Data included in this release are from Pacific sand lance and water, sediment and suspended particulate matter collected at two sites in Puget Sound, Washington, which were evaluated for PCB concentration. PCB congener data are stored in the U.S. Fish and Wildlife Service’s Environmental Contaminant Data Management System (ECDMS), accessible through the Wildlife & Environmental Contaminants Mapper (https://ecos.fws.gov/ecdms4/). The ECDMS is a searchable database, and records can be exported as Excel files. Data in this data release are included in two ECDMS Catalog Numbers: G08003 and G08004.
