Summary

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7513WCB. These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset has five comma separated values (.csv) file exported from a Microsoft Access relational database. The data consist of percent cover and point contact data from algae and invertebrates at intertidal rocky substrate sampling sites. Tables include: 1) intertidal cover, 2) intertidal percent cover, 3) intertidal top layer percent cover, 4) intertidal substrate percent cover, and 5) taxonomic classification table.

Purpose

These data provide percent cover and point contact data for algae and sessile invertebrates on sheltered rocky shorelines to assess change in intertidal invertebrate communities on rocky shorelines. Sampling was conducted within regions of Alaska including: Kenai Peninsula (KEP; Kenai Fjords National Park), Alaska Peninsula (AKP; Katmai National Park and Preserve), and Prince William Sound (PWS; northern, western, and eastern Prince William Sound). Study site locations are described in the "Monitoring Site Locations" data release: https://doi.org/10.5066/F78S4N3R (Coletti et al. 2017).
