WHOI Pea Island Walking Surveys and Bathymetry 2020-2021
Data provider
Woods Hole Oceanographic Institution - Peter Traykovski
Location
Pea Island National Wildlife Refuge, Dare County, NC
Summary
Peter Traykovski (WHOI) collected five days of data: 2020-11-22, 2020-11-25, 2020-11-27, 2021-04-19, 2021-04-20. Small surf vehicle was used to collect bathymetry up to 15 m. Backpack walking surveys with continuous GPS successfully mapped the beach. Data collected happened to be in the same location as the DUNEX experiment completed in in 2021 (see 2021-028-FA and 2021-029-FA) and was donated to the USGS as a way to have a longer time series on the field site topobathy at Pea Island. Bathymetry and topography also collected at the southwest section of the Basnight Bridge where it is eroding to see if that would be a feasible study site for DUNEX change during a storm.
Info derived
Bathymetry, topography.
Comments
Data is for a pre-survey of the Pea Island DUNEX site (2021-029-FA, 2021-028-FA) and takes place in the same location. Data donated by Peter Traykovski of WHOI
A JAVAD Triumph-2 GNSS receiver (https://www.agt-dz.com/en/shop/product/javad-triumph-2-gnss-receiver-594?category=7#attr=) was used to collect elevation data relative to a base station. Raw data is XYZ information as a txt file and data points are interpolated to create a low resolution DEM.
