San Salvador Island is located on an isolated carbonate platform situated on the southeastern edge of the Bahamian Archipelago. Over half of the island's small area is covered by hypersaline lakes that expose the island's water table to evaporation. Many of the island's lakes are connected to the ocean by karst conduits, thereby allowing tidal pumping to drive the exchange of fresh and saltwater during tidal cycles. To investigate the influence of tidal cycles on lake water levels, we monitored water temperature, pressure, and specific conductivity for several lakes located on San Salvador Island, Bahamas. We instrumented lakes with HOBO Onset U20L-04 loggers with a water level accuracy of 0.14 cm. HOBO Onset data loggers were set to record measurements at intervals ranging from 30 seconds to 15 minutes. We chose sampling intervals as to not exceed the HOBO logger's data recording capacity based on our estimated return to the site to download data. For most of the lakes instrumented in this study, we combine multiple timeseries into an individual location file. Accordingly, a single data table may have temporal data gaps and time periods with different sampling intervals. The README.md file included with this dataset contains a table with lake names and locations, sampling rates, and deployment dates.

Chloride Concentrations, Conductivity, and Water Temperature Data from Upper Yahara River Watershed Tributaries in Dane County, WI: December 2019 – April 2021
Conductivity and chloride were measured for 2 years in nine tributaries of Lake
Mendota and Lake Monona in Dane County, WI. HOBO Conductivity loggers continuously
measured absolute conductivity and water temperature every 30 minutes. Breaks in
data collection were due to a calibration period or if the loggers were out of the
water. Grab samples for chloride concentration occurred weekly or biweekly.
Conductivity and water temperature were measured with a field meter at each sampling
excursion. This data was needed for a master’s research thesis with the goal of
characterizing the spatial distribution and loading of chloride in the Upper Yahara
River Watershed.

Lake level is measured during the open water season for the seven primary lakes in the Trout Lake area (Allequash, Big Muskellunge, Crystal, Sparkling, and Trout lakes and unnamed lakes 27-02 [Crystal Bog], and 12-15 [Trout Bog]) using Solinst level loggers in stilling wells logging at 30 minute intervals. Lake level elevation is also manually measured several times each season using a survey of benchmarks of known elevation to calibrate the level loggers. Prior to 2017, lake level was measured with staff gauges placed near the shoreline. Staff gauges were read every two weeks as part of LTER routine sampling. Values presented in the database are the water elevation in meters above sea level. Sampling Frequency: before 2017, every two weeks. 2017 to present, every 30 minutes. Number of sites: 7.more » « less

We monitored water quality in Carvins Cove Reservoir (Roanoke, Virginia, USA) with high-frequency (10-minute) sensors in 2020-2023. Carvins Cove Reservoir is owned and managed by the Western Virginia Water Authority as a primary drinking water source. This data package consists of datasets from two separate deployments. First, from July 2020 - August 2021, depth profiles of water temperature were measured on 1-meter intervals using HOBO temperature pendant loggers deployed from 0.1 m below the surface of the reservoir to 10 m depth, and also at 15 and 20 m depth. Additionally, water temperature was measured in the Sawmill Branch inflow at 0.5 m depth using HOBO temperature pendant loggers. Second, from 9 April 2021 - 31 December 2023, depth profiles of water temperature were measured on 1-meter intervals from 0.1 m below the surface of the reservoir to 11 m depth and additionally at 15 and 19 m. A YSI EXO2 sonde measured water temperature, conductivity, specific conductance, chlorophyll a, phycocyanin, total dissolved solids, dissolved oxygen, and fluorescent dissolved organic matter at ~1.5 m depth. A YSI EXO3 sonde measured water temperature, conductivity, specific conductance, total dissolved solids, dissolved oxygen, and fluorescent dissolved organic matter at 9 m depth, which corresponds to the depth of a water outtake valve. The thermistors, EXO3 sonde, and pressure sensor were deployed at stationary, fixed elevations (referred to as positions) deployed off of the dam near the water outtake valves. Due to variable water levels in the reservoir, the depths of these sensors varied over time. In contrast, the EXO2 was deployed on a buoy from 2021-2022 and remained at 1.5 m depth as the water level fluctuated. However, in 2023, the buoy disappeared in a storm, after that the EOX2 was deployed at a stationary elevation as the water level fluctuated around the sensor. At the monitoring site, the reservoir is approximately 19 m deep (reservoir maximum depth is 23 m).more » « less

Water chemistry is measured annually in 11 monitoring wells to characterize regional groundwater chemistry in the Trout Lake area. The chemical parameters measured include pH, conductivity, total alkalinity, disolved inorganic and organic carbon, total nitrogen, nitrae, ammonia, total phosphorus, calcium, magnesium, soium, potassium, chloride, sulfate, iron, manganese, total silica and dissolved reactive silica. Chemical data areavailable at a quarterly sampling frequency for some years. In addition (see related data set - Groundwater Level), water levels in 37 monitoring wells are measured several times per year. The wells are scattered throughout the Trout Lake hydrological basin and the data are used to calibrate and test regional groundwater flow models. Sampling Frequency: annually - with some earlier data from quarterly sampling Number of sites: 11more » « less

Parameters characterizing the major ions of the eleven primary lakes (Allequash, Big Muskellunge, Crystal, Sparkling, Trout, bog lakes 27-02 [Crystal Bog], and 12-15 [Trout Bog], Mendota, Monona, Wingra and Fish) are measured at one station in the deepest part of each lake at the top and bottom of the epilimnion, mid-thermocline, and top, middle, and bottom of the hypolimnion. These parameters include chloride, sulfate, calcium, magnesium, sodium, potassium, iron, manganese, and specific conductance (northern lakes only). Lake Wingra has always been just a surface sample, but in the winter we have, at times, taken chloride samples from top to bottom to have a better understanding of road salt effects. Samples for conductivity are collected four times per year in the seven primary lakes (Allequash, Big Muskellunge, Crystal, Sparkling, and Trout lakes, and unnamed lakes 27-02 [Crystal Bog], and 12-15 [Trout Bog] in the Trout Lake area at the deepest part of the lake, sampling at the surface, mid water column, and the bottom. The sampling dates include February under ice, spring mixis, August stratified, and fall mixis. Conductivity is measured using a YSI Model 32 conductivity meter with YSI 3403 conductivity cell, reported as uS/cm at 25°C. 1981-1988: a Sybron Barnstead conductivity bridge was used. 1981-1986: conductivity was measured monthly. Sampling Frequency: quarterly (winter, spring and fall mixes, and summer stratified periods) Number of sites: 11more » « less
