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 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.
The data set includes temperature data from the base of the water column and below the bottom of the Indian River Lagoon, Brevard County, Florida. Data were collected near Eau Gallie, Melbourne, Florida and Riverwalk Park, Rockledge, Florida, on the western shore of the Lagoon. These data will ultimately be used to evaluate groundwater seepage. Data collection includes, temperature profiling using temperature stakes and distributed temperature sensing. Temperature stakes consist of 4 to 5 temperature sensors imbedded in 0.6 to 0.9 meter long polyvinyl chloride stakes that are designed to be driven into the sediment at the bottom of the lagoon. Temperature data were collected hourly at a resolution of 0.0625...

This dataset contains the selected physical properties and chemical constituents that were measured at Puerto Mosquito, Isla de Vieques on June 22, 2017. A cross-sectional profile was conducted by measuring a total of ten selected site throughout the lagoon during the morning. Field water-quality measurements included the parameters of specific conductance, and dissolved oxygen.

The dataset contains the selected physical properties and chemical constituents that were measured at Caño Boquerón, Cabo Rojo, and Puerto Mosquito, Isla de Vieques, Puerto Rico during a diurnal cycle. Two diel studies were conducted per lagoon to determine the community primary productivity. Photosynthesis creates oxygen which enhances microbiological activity and results in the production of organic matter. Primary productivity is important for supporting the food web in aquatic ecosystems. The field data collection included the measurement of temperature, dissolved oxygen, and percent of oxygen saturation. Measurements were obtained at about 1 hour intervals. Diel studies were conducted on October 29, 2015 and...
The dataset includes estimates of salinity using specific conductance measurements at 1) Caño Boquerón, Cabo Rojo, and 2) Puerto Mosquito, Isla de Vieques; Puerto Rico for the period from July 2015 to July 2016. This dataset 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 (disturbed conditions); and Puerto Mosquito (undisturbed conditions). Monthly measurements of specific conductance were collected at both...
Lakes in the County of San Diego, California, USA.
The U.S. Geological Survey, in cooperation with the City of South Padre Island, Texas, collected baseline seagrass, benthic invertebrate, and water-quality data for a near-shore area of the Laguna Madre near South Padre Island in July 2021. Sample and data collection points were located within a grid consisting of eight transects and three sampling points on each transect. The data included in this data release are presented in a comma-separated values (csv) file format.
