This dataset is a point shapefile containing water-depth points collected during a sedimention survey of Lago Guayabal conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. More than 270,000 water-depth points were surveyed along 60 navigation lines used in previous sedimentation surveys (Soler-Lopez, 2003, 2007, 2008). All water-depth data were collected using a Teledyne-Odom Echotrac CVM depth sounder coupled to a Global Positioning System...

A secchi disk is used to estimate the water transparency depth of surface-water bodies. Secchi disk depth was measured monthly at Caño Boquerón, Cabo Rojo, and Puerto Mosquito, Isla de Vieques; Puerto Rico for the period from July 2015 to July 2016. This data release is part of a limnological analysis at Caño Boquerón and Puerto Mosquito to assess the principal factors affecting the hydrology and water-quality conditions. In addition, the study provides baseline information to regulatory agencies responsible for the management and conservation of coastal waters in Puerto Rico. The investigation focused on Caño Boquerón, and Puerto Mosquito surface-water bodies, representing disturbed and undisturbed conditions,...

This dataset consists of a shapefile of points corresponding to water depth collected for the bathymetric survey of Puerto Mosquito, in Isla de Vieques, Puerto Rico, on August 11, 2015. The U.S. Geological Survey, in cooperation with the Puerto Rico Environmental Quality Board, conducted a limnological study at Puerto Mosquito in Vieques to assess the principal mechanisms affecting the hydrology and water quality characteristics. The study characterized hydrologic and physical-chemical properties, sediment deposition rates, bathymetry, and biological conditions. The bathymetric survey system used for the study consisted of coupling a global positioning system (GPS) device with a water depth sounder. Established...

This dataset is a polyline shapefile containing bathymetric contours, at 1-meter intervals, of Lago Guayabal, Villalba, Puerto Rico. The contours were generated from bathymetric data collected during a sedimentation survey conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. Field techniques used during the survey were similar to those outlined by Soler-López (2008) and Wilson and Richards (2006). More than 270,000 water-depth points were surveyed...

This dataset contains measurements of dissolved oxygen concentrations collected at Caño Boquerón in Cabo Rojo, and Puerto Mosquito, Isla de Vieques, Puerto Rico. The method consists of in-situ incubation of two light-and-dark bottles for approximately four hours. Dissolved oxygen concentrations were determined using the Winkler method. A total of twelve monthly in-situ incubations were conducted from July 2015 to July 2016. For each bottle incubated, two or three titrations were conducted and an average of the DO calculations is presented.
