Description:

Abstract:

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and describe bivalve count and size sampling and observations conducted at intertidal soft-sediment sampling sites in the northern Gulf of Alaska. This dataset consists of five comma separated files (.csv): 1) bivalve taxonomy table, 2) bivalve sampling site table, 3) bivalve count table, 4) bivalve size table, and 5) list of Gulf Watch Alaska principal investigators and collaborators.

Purpose:

The purpose of this long-term project is to assess change in intertidal bivalve communities on mixed sediment beaches. These data are also used to assess changes in abundance, size distribution, and growth rate of larger bivalve species.

Sampling was conducted within regions of Alaska including: Kenai Peninsula (KEP; Kenai Fjords National Park), Kachemak Bay (KBAY), 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 versioned data release supersedes one previous nearshore soft-sediment bivalve USGS data release (https://doi.org/10.5066/F71834N0). The data provided in this release includes all data from the past release, as well as new data collected after 2015. This data release will continue to be updated as new data are collected each sampling year.

Data_Set_Credit:

Many people (USGS staff, contractors, and volunteers, NPS staff and volunteers, University of Alaska Fairbanks staff and students, and NOAA staff) contributed to collection of the bivalve observations contained in this data set. The Nearshore Component Principal Investigators involved in this effort include: Heather Coletti, Dan Esler, Brenda Ballachey, James Bodkin, Thomas Dean, George Esslinger, Katrin Iken, Kim Kloecker, Brenda Konar, Mandy Lindeberg, Daniel Monson, Brian Robinson, Sarah Traiger, Ben Weitzman, and Dominic Hondolero.

Native_Data_Set_Environment:

The original data are stored as a Microsoft Excel spreadsheet in a Windows operating environment. Data are exported as comma separated text files (.csv) for dissemination.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Quality Assurance and Quality Control (QAQC) protocols for these data included: 1) entering site, identification, and size data into the spreadsheet while in the field on the day of sample collection, 2) bivalve 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 soft-sediment sampling were checked against the database.

Logical_Consistency_Report:

All attribute values fall within expected ranges. Count and size 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 soft-sediment sampling are checked against the database.

Completeness_Report:

(1) Western Prince William Sound (WPWS) sites were not sampled in 2009. (2) Katmai National Park and Preserve (KATM) sites were not sampled in 2011. (3) Nuka Bay, Kenai Fjords National Park was not sampled in 2021. (4) Zero tide time and survey start time were not recorded before 2017. In 2017 these times were only recorded at Jakalof Bay (KBAY) and Aialik Bay (KEFJ). These times were recorded at all sites in 2019. These times were recorded at all sites except the KBAY sites in 2021. (5) Foraging pits were only counted in 2017 at the KBAY sites. Foraging pits were counted at all sites in 2019. Foraging pits were not counted at the KBAY sites in 2021. (6) Mytilus trossulus was not sampled at Katmai National Park and Preserve (KATM), Kenai Fjords National Park (KEFJ), and Western Prince William Sound (WPWS) before 2015. (7) McCarty Fjord was not sampled in 2023 due to inclement weather.

Methodology:

Methodology_Type: Field
Methodology_Description:

Sampling was conducted in sheltered soft-sediment habitats within regions of Alaska including: Kenai Peninsula (KEP; Kenai Fjords National Park), Alaska Peninsula (AKP; Katmai National Park and Preserve), Prince William Sound (PWS; northern, western, and eastern Prince William Sound), and Kachemak Bay (KBAY). Site locations are included with this data package "KBAYKATMKEFJWPWS_2007-2023_Soft_Sediment_Bivalve_Site_Info.csv" and site location details are in the data release: https://doi.org/10.5066/F78S4N3R (Coletti et al. 2017).

At each site a 50 or 100 meter transect was positioned horizontally along the beach at the 0 Mean Lower Low Water level (MLLW) or plus 0.5-meter tide level. A random starting point was chosen and twelve 0.25 meter-square quadrats were placed systematically along the transect and were excavated to a depth of 25 centimeters. All sediments were sieved through a 10-millimeter mesh screen and all bivalves were identified to the lowest possible taxa and counted. We used dial or electronic calipers to measure bivalves to the nearest millimeter along the longest point of the shell.

Sediments were returned to the quadrat after the sieving process was complete.

A U.S. Geological Survey data release containing site location information for intertidal studies.

Process_Step:

Process_Description:

Field data recorded on paper field data sheets and then entered into a Microsoft Excel spreadsheet. This was usually completed while still in the field or back at the support vessel, but not actually on the bivalve sampling site. Data are .csv outputs from the database.

Process_Date: Unknown

Process_Step:

Process_Description:

Field data sheet QAQC: the field crew and then a field data manager review the data sheets for missing, illegible, or confusing entries and correct any issues.

Process_Date: Unknown

Process_Step:

Process_Description:

Spreadsheet QAQC: bivalve sampling site information, counts and sizes are checked against the field data sheets and also checked row by row and cell by cell for accuracy and completeness.

Process_Date: Unknown

Process_Step:

Process_Description:

Spreadsheet QAQC: site, count and measurement data are checked against the field data sheets for completeness and logical consistency and data are checked for outliers.

Process_Date: Unknown

Spatial_Data_Organization_Information:

Indirect_Spatial_Reference:

The only spatial information in these data are the named locations for the sampling sites and the site ID code. Sites are documented with start and end coordinates and are also referred to by name (e.g., Herring Bay sampling site) and code (e.g., PWS_B08_SI_05). Please refer to Coletti et al. 2017, a USGS data release that provides geographic coordinates of all sites: https://doi.org/10.5066/F78S4N3R
