Summary

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset is comprised of six comma separated values (.csv) file exported from a relational database. The data consist of 1) summer marine bird and mammal densities, 2) winter marine bird and mammal densities, 3) summer marine bird and mammal observations, 4) winter marine bird and mammal observations, 5) summer marine bird and mammal survey strip transects, and 6) winter marine bird and mammal survey strip transects.

Purpose

The purpose of the surveys is to provide data to estimate the species composition, relative abundance, and distribution of all marine birds and mammals within the nearshore zone of southcentral Alaska. The focus of these surveys is on marine birds that are trophically linked to the kelp/benthic invertebrate nearshore food web. Because other birds and mammals are encountered in the course of these surveys, observations of all marine birds and mammals are recorded. Specifically, the objective of this task is to assess changes to long-term trends in the seasonal abundance of birds and mammals along the coast of Alaska. Data were collected from strip transects at sites nested in three sampling blocks: Kachemak Bay National Estuarine Research Reserve, Katmai National Park and Preserve, and Kenai Fjords National Park. The location of sampling blocks are described in Coletti et al. 2017: https://doi.org/10.5066/F78S4N3R.
