This record provides dissolved inorganic nutrient and human dietary tracer (caffeine and sucralose) concentration metrics collected monthly between May 2023 to May 2024 to provide reference data of nearshore and watershed water quality on the island of Culebra, Puerto Rico. The water quality monitoring was conducted at 18 fixed stations. Five stations were selected to quantify Land Based Sourc...
The data described here are structural complexity estimates derived from Structure-from-Motion (SfM) benthic habitat imagery from diver transect surveys conducted at stratified-random sites (StRS) by the Pacific Islands Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD) as part of the NOAA National Coral Reef Monitoring Program (NCRMP). The coral reef photos, collected by scuba...
This metadata record describes Acropora globiceps and Isopora crateriformis raw density at the site level as well as colony-level partial mortality, size, and bleaching, and a classifier for each species. Surveys were conducted by SCUBA divers from February 4th-26th, 2025 and March 10th-27th, 2025 in Tutuila, American Samoa by scientists of the Ecosystem Sciences division at the Pacific Islan...
Building on previous and ongoing work at China Camp State Park, this project provided field data, vulnerability assessments and community engagement to advance toward selecting adaptation strategies to protect and enhance natural resources and archaeological and tribal cultural resources while accommodating ongoing utilization of an important shoreline road subject to regular coastal and storm...
In October 2018, Quantum Spatial (QSI) was contracted by the United States Geological Survey (USGS) to collect high resolution topobathymetric Light Detection and Ranging (LiDAR) data in the winter of 2018 for the USGS Gulf Coast sites in the Gulf of Mexico. The USGS Gulf Coast project area covers approximately 174 square miles and is comprised of three main areas of interest; Chandeleur Island...
A transfer project brought low-cost arm-and-float water level loggers and tidal calculation expertise to seven reserves to help characterize flooding dynamics for different marsh habitat features and inform targeted management activities. The Project Reliable water level information is vital for understanding how tidal flooding and inundation affect coastal wetlands. Despite the rich body o...
