Rocky Intertidal Invertebrate and Algae Cover from Prince William Sound, Katmai National Park and Preserve, and Kenai Fjords National Park

In 2011, sites in Katmai (AKP site codes) were not sampled. In 2020, no sites were sampled due to the Covid-19 pandemic. In 2021, KEP_B5_RI_03 Nuka Bay was not sampled due to weather. In 2021, AKP_B10_RI_03, 1.5 m quadrat 8 is missing because of computer issues. In 2021, WPWS_01: 11 quadrats for 1.5 m are missing because of computer issues. 11 quadrats for 0.5 m are missing because Q10 was on a steep wall and could not be sampled. In 2021, WPWS_01, 0.5 m, Q1 is missing 1 point and Q5 is missing 3 points. In 2022, AKP_B10_RI_02 is missing some replicates because the site was sampled on a +0.2 m MLLW tide day due to weather. In 2022, at KEP_B05_RI_03 there was a landslide that affected the site including the end of the 1.5 m transect. In 2022, no percent cover for quad M9 quads U9-10 at PWS_B08_RI_01 was recorded, because the quadrats were on a steep cliff that could not be accessed at high tide. In 2022, KEP_B05_RI_04, quad U1 only has 23 points for percent cover because the HOBO logger was under two points. In 2022, an error was found error in "Top Layer" data where species observed in “Point 99” (not observed under the 25 points used for percent cover), incorrectly making the percent cover for some quadrats add up to more than 100. These species were removed to correct the percent cover to 100 percent. In 2023, KEP_B05_RI_02 was not sampled due to inclement weather.
