Description:

Abstract:

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset has four comma separated values (.csv) file exported from a Microsoft Access relational database. The data consist of: 1) size and disease state of sea stars, 2) counts of sea stars, 3) taxonomic classification and 4) Gulf Watch Alaska contributors.

Purpose:

These data provide sizes, counts, density, and disease state of sea stars at sites in sheltered rocky habitats. These data are used to estimate density of healthy and diseased sea stars and sea star size frequency 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).

Supplemental_Information:

This dataset is a component of the nearshore monitoring portion of the Gulf Watch Alaska (GWA) program. There are multiple datasets associated with the rocky site sampling; see "KATMKEFJWPWS_2006-2023_Rocky_Intertidal_Sampling_Project_Metadata" for a list of all associated datasets.

Two additional closely related USGS Data Releases from these sampling locations are available: (1) temperature logger data (https://doi.org/10.5066/F7WH2N3T) and (2) mussel (Mytilus) sampling (https://doi.org/10.5066/F7FN1498).

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Quality Assurance and Quality Control (QAQC) protocols for these data included: 1) entering identification data directly into the electronic databases in the field, thus avoiding transcription errors while copying from data sheets, 2) algae and invertebrate names were verified and standardized by using drop-down lists on electronic data entry forms, 3) data were proofed and edited immediately after each site was sampled and before beginning a new site, 4) all records were checked for missing values, duplicates, outliers, and inconsistencies, and 5) field notes and other data sheets associated with rocky intertidal monitoring were checked against the database.

Counting diseased and healthy sea stars began in 2019. Observers were trained on identification of sea star wasting symptoms using the ID guide at https://marine.ucsc.edu/data-products/sea-star-wasting/#id-guides. Only presence of symptoms is recorded, severity of symptoms is not recorded.

Logical_Consistency_Report:

Attribute values fall within expected ranges. Count data were entered electronically in the field, rather than being recorded on datasheets to prevent transcription errors. After a site has been sampled, the data were proofed and edited in the field before beginning a new site. Field notes and other data sheets associated with rocky intertidal monitoring are checked against the database.

Completeness_Report:

In 2011, none of the AKP (Katmai) sites were sampled. In 2021, no data were collected at KEP_B5_RI_03 Nuka Bay due to weather. In 2022, AKP_B10_RI_02 star swath was not sampled because the site was sampled on a +0.2 m MLLW tide day, due to weather. In 2023, KEP_B05_RI_02 was not sampled due to inclement weather.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Transects for rocky intertidal sampling are marked with stainless steel eye-bolts and a site ID marker plate to ensure consistency in sampling location. Additionally, several eye-bolts are placed along the transects' horizontal lengths to ensure similar placement of the lines. Coordinates are not recorded for each eye-bolt. Tide prediction software and GPS clock and location data (approximately 4 m accuracy) are used to estimate 0 MLLW for the sea star swath lower boundaries, but coordinates were not recorded. Rather, each year when re-sampling the site, the same tools are used to conduct the sea star swath count.

Lineage:

Methodology:

Methodology_Type: Field
Methodology_Description:

Sea stars were counted along 50 meter long swaths at each of the randomly selected sites within sheltered rocky shorelines. The lower edge of the transect was placed at 0 MLLW (mean lower low water). Star swath sizes were varied in the early years of this monitoring project from 4 m wide X 100 m long to 4 m wide X 50 m long. The 4 m X 50 m swath size was chosen for all future sampling.

Entity_Type_Label: KATMKEFJWPWS_2006-2023_Sea_Star_Count.csv
Entity_Type_Definition:

Table with counts of sea stars at rocky intertidal sampling sites used to estimate the density of sea stars at rocky intertidal sites. Each record is the count of sea stars at a single rocky intertidal sampling site. Presented in a Comma Separated Value (CSV) formatted table exported from a relational database.
