These data were collected as part of the Great Lakes Restoration Initiative (GLRI) project template 678-1 entitled "Evaluate immediate and long-term BMP effectiveness of GLRI restoration efforts at urban beaches on Southern and Western Lake Michigan". This project is evaluating the effectiveness of projects that are closely associated with restoration of local habitat and contact recreational activities at two GLRI funded sites in Southern Lake Michigan and one non-GLRI site in Western Lake Michigan. Evaluation of GLRI projects will assess whether goals of recipients are on track and identify any developing unforeseen consequences. Including a third, non-GLRI project site in the evaluation allows comparison between...
This dataset describes the identification of phytoplankton to the lowest taxonomic level (typically species), as well as abundance (density) and biovolume from grab samples collected from Lake Michigan at Jackson Park at Hyde Park, Illinois and Lake Michigan at Jeorse Park at Gary, Indiana.
Water-quality constituents were measured along planned survey lines, which were generally perpendicular to the shoreline and spaced 100 meters apart, over an approximately 2.3-mile section of nearshore Lake Erie on June 10-12, 2019 (survey 1), and August 19-21, 2019 (survey 2), using a YSI 6920 V2 multiparameter sonde towed from the side of a marine survey vessel at about 1-ft depth. Water-quality data collected in this area included near-surface measurements of water temperature, specific conductance, pH, dissolved oxygen, and turbidity. The water-quality data were measured at 5-second intervals and were geo-referenced with a global navigation satellite system (GNSS) smart antenna with submeter accuracy. There...

Historically, the high potentiometric surface of groundwater in the Silurian/Devonian carbonate aquifer in Monroe County, MI resulted in discharge of highly mineralized, SO4-rich groundwater to the Lake Erie shoreline near both Erie State Game Area (ESGA) and Pointe Mouillee State Game Area (PMSGA). Recently, regional groundwater levels near PMSGA have been drawn down as much as 45 m below lake level in apparent response to quarry dewatering. From August to November of 2003, we conducted preliminary studies of groundwater flow dynamics and chemistry, shallow lake water chemistry, and fish and invertebrate communities at both sites. Consistent with regional observations, groundwater flow direction in the nearshore...

The bathymetry data was collected by the Hawaii Coastal Geology Group of the University of Hawai'i, Manoa in August of 2017 for USGS. A Garmin echoMAP Chirp was used to collect the data. 1 site along the western (lagoonside) and 2 at the lagoon entrance on the northern (ocean side) of the atoll was surveyed.
Continuous measurements of nearshore currents in Lake Erie in the vicinity of Villa Angela Beach and Euclid Creek, Cleveland, Ohio, were recorded during the summer of 2019. Currents were measured every 15 minutes with a 5-minute averaging interval using two different acoustic Doppler velocity meters (ADVM). The first instrument (ADVM 1) was a SonTek 500 kHz Argonaut-SL ADVM mounted to the northwest side of the southwest caisson near the entrance of Wildwood Marina about 8 feet above the bed (approximately mid-depth at the time of installation) at a true heading of 307 degrees. ADVM 1 was configured with a 6.6-ft blanking distance, ten 33-ft measurement cells, and a total profiling distance of 335 feet from the face...
