Seabird Diet Data Collected on Middleton Island, Gulf of Alaska

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and contain diet data from Black-legged Kittiwakes (BLKI), Rhinoceros Auklets (RHAU), and Tufted puffins (TUPU) located on Middleton Island in Prince William Sound, Gulf of Alaska. The first table consists of information on seabird diet samples including the sampling method and number of prey types identified per sample ("seabirdDiets_foodSample_middletonIsland.csv"). The second table is similar to the first table, however, the samples have been subdivided by individual prey species ("seabirdDiets_samplePrey_middletonIsland.csv"). The third table consists of information specific to sampled prey items, such as prey taxa identification...

Black Oystercatcher Morphology and Primary Feather Lengths in Alaska and British Columbia, 2019-2022

These data provide morphological measurements and primary feather length measurements of Black Oystercatcher (Haematopus bachmani) captured at several sites across Alaska and British Columbia between 2019 and 2022. The first table contains mass and morphological measurements of body and bill size. The second table provides lengths of individual primary feathers measured from folded wing photographs using a computer software. These feather lengths are to be used in a size-constrained components analysis to calculate wing shape such as pointedness and convexity.

Literature Review of Lithophilic-Spawning Fishes Egg Collection Methods

Assessment of egg deposition is widely used to provide an index of spawning efforts for lithophilic-spawning fishes. However, little is known about the collection techniques efficacy and bias when collecting fish eggs. We conducted a literature review to assess egg collection methods and evaluate egg retention and capture on egg mats. The literature review provided a summary of different gear types used to collect fish eggs, possible bias from the gears, and egg 'abundance' reporting strategies.

Collections inventory for the U.S. Geological Survey Woods Hole Coastal and Marine Science Center Samples Repository (ver. 2.0, September 2023)

Since 2002, the Woods Hole Coastal and Marine Science Center’s Samples Repository supports research by providing secure storage for geological, biological, and geochemical samples; maintaining organization and an active inventory of these sample collections; and providing access to these collections for study and reuse.This collections inventory has been compiled, organized, and released as a searchable database to provide researchers and the general public with means to discover and request scientific sample material preserved and maintained by the Woods Hole Coastal and Marine Science Center Samples Repository. Updates are made to the inventory as the collections grow, and version history information is available...
