Anchorage, Alaska municipality Elodea Points Surveyed

공공데이터포털

This tabular dataset contains information pertaining to the presence or absence of Elodea at randomly selected sites within the littoral zone of prioritized lakes within the Anchorage, Alaska municipality area. Data were acquired through the use of ESRI's FieldMaps application. Visual observations and rake throws within a 10 meter by 10 meter area were used to evaluate the presence of Elodea following the sampling protocol outlined in "Fulkerson, J. (2023). Standard Operating Procedure for Elodea Detection in Alaska Lakes. Alaska Center for Conservation Science".

Anchorage, Alaska elodea survey proposed sampling locations

공공데이터포털

Collection of tabular data sets (.csv) containing year-specific proposed sampling points within inland waterbodies of the Anchorage, Alaska municipality. In 2023 and 2024, proposed sample sites were created using ArcGIS tool developed by and detailed in the Fulkerson 2023 SOP 1 using waterbody boundaries defined by NHD Plus data. In future years, sample points are selected using NHD Plus waterbody boundaries, dropping grids over the waterbody (50 meter cell sizes for lake boundaies less than 3 kilometers; otherwise 100 meters), and selecting random sites within the littoral zone. Litorral zones are defined by creating a 150 meter buffer from the lake boundary and any depths less than 30 feet as designated by lake bathymetry layers.

Anchorage, Alaska Municipality Elodea Infestation Extent Polygons

공공데이터포털

This polygon layer contains extents of Elodea infestations identified within the Anchorage, Alaska municipality. Polygons were created in the field using the ESRI's Field Map application. Sampling protocol follows "Fulkerson, J. (2023). Standard Operating Procedure for Elodea Detection in Alaska Lakes. Alaska Center for Conservation Science". Once Elodea were detected at a given site, the crew will delineate the extent of the Elodea infestation, either visually or using rake throws and draw a polygon in the Field Map application delineating the extent of a given infestation.

Point Sampling Data from Eelgrass (Zostera marina), Seaweeds and Selected Invertebrates at Six Embayments and Two Islands at the End of the Alaska Peninsula

공공데이터포털

This dataset is from surveys for the abundance and distribution of eelgrass and seaweeds that were made at six embayments and two offshore islands at the southwestern end of the Alaska Peninsula in August-September 2012. The five tables provide information on percent cover and location of eelgrass and seaweeds, presence and absence of selected invertebrates, locations of eelgrass genetic samples, and environmental conditions within surveyed sites.

Environmental DNA detection data of Northern pike (Esox lucius) using a portable, field-based platform and a lab-based platform

공공데이터포털

We tested the sensitivity of a portable, field-based environmental DNA (eDNA) platform relative to widely used lab-based eDNA approaches for detecting invasive northern pike (Esox lucius) in eight lakes on Alaska’s Kenai Peninsula. Raw data reported in this dataset report detect/non-detect data for technical replicates of water samples.
