Tropical Coral Reefs of the World

Reef locations are based on 500 meter resolution gridded data (converted to polygon) reflecting shallow, tropical coral reefs of the world. Organizations contributing to the data and development of the map include the Institute for Marine Remote Sensing, University of South Florida (IMaRS/USF), Institut de Recherche pour le Développement (IRD), UNEP-WCMC, The World Fish Center, and WRI. The composite data set was compiled from multiple sources, incorporating products from the Millennium Coral Reef Mapping Project prepared by IMaRS/USF and IRD.

Microsatellite genotypes for Lake Sturgeon (Acipenser fulvescens) Eggs and Larvae from Constructed Reefs in the St. Clair-Detroit River System (2015-2016)

This dataset contains the physical collection information (e.g., sample location, date, gear type) and microsatellite DNA genotype of egg and larval Lake Sturgeon collected in the St. Clair and Detroit rivers in 2015 and 2016. Individuals were genotyped for 18 microsatellite loci (13 disomic and 5 polysomic). Alleles (base pair sizes) were recorded as presence absence scores (1:present, 2:absent, 0:missing data) for all previously observed alleles. Thus individual genotypes were recorded as pseudo diploid dominant phenotypes resulting in individual vectors of length n=205 for each genotyped egg or larval individual.

Coral clasts noted in 2008 to 2017 that pertain to sea floods of the past 1,000 years on Anegada, British Virgin Islands

This part of the release provides an updated georeferenced catalog of coral boulders and cobbles pertaining to extreme waves on Anegada, a low Caribbean island perched south of the Puerto Rico Trench. The main taxa listed are the boulder star coral Orbicella franksii (37 localities), brain coral Pseudodiploria strigosa (171), elkhorn coral Acropora palmata (36), mustard hill coral Porites astreoides (29).

World Coral Bleaching Occurrences

The ReefBase Coral Bleaching dataset provides observation details of coral bleaching occurrences (or lack thereof) around the world. This dataset was built upon an original bleaching database developed at UNEP-WCMC, and has been maintained and updated regularly by ReefBase since early 2002. Main sources of information for this dataset have been: published records from the literature, postings on the coral-list (http://www.coral.noaa.gov/lists/), the ReefBase online Bleaching Report (http://www.reefbase.org/contribute/bleachingreport.aspx), and through collaborations with numerous institutions and individuals. ReefBase would like to particularly acknowledge the contributions made by: National Oceanographic and Atmospheric...

Remote Sensing Coastal Change

Remote-sensing technologies—such as video imagery, aerial photography, satellite imagery, structure-from-motion (SfM) photogrammetry, and lidar (laser-based surveying)— can be used to measure change along U.S. coastlines. Quantifying coastal change is essential for calculating trends in erosion and accretion, evaluating processes that shape coastal landscapes, and predicting how the coast will respond to future natural disasters (e.g. hurricanes, landslides, wildfires) and longer term climate trends such (e.g. sea-level rise, ecosystem change, coral bleaching), all critical for U.S. coastal communities. Rapid developments have occurred in remote-sensing technologies during the 21st century. With collaborators...
