Natural cave passages penetrating a coastal aquifer in the Yucatan Peninsula (Mexico) were accessed to test the hypothesis that chemoclines associated with salinity gradients (haloclines) within the flooded cave networks of the karst subterranean estuary are sites of methane oxidation. Two field trips were carried out to the fully-submerged cave system located 6.6 km inland from the coastline in January 2015 and January 2016. Vertical chemical profiles across the water column haloclines were obtained using the OctoPiPi (OPP), a high-resolution water sampler built by the U.S. Geological Survey (USGS). The sampling efforts resulted in cm-scale profiles of major ions (e.g., chloride and sulfate), as well as concentrations...
Airborne electromagnetic (AEM) and magnetic survey data along four flight lines were collected in Everglades National Park, Florida as part of a larger survey. Data were collected during October 2001. These lines, totaling 95.2 line-kilometers, repeated the path of four lines from earlier AEM survey collected in December 1994 (released under USGS Open-File Report 02-101 downloadable at https://pubs.er.usgs.gov/publication/ofr02101). Electromagnetic data were acquired with Dighem VRES frequency-domain system. Magnetic data were collected with a Scintrex CS2 cesium-vapor magnetometer. The nominal elevation of the electromagnetic system was 30 m. This data release includes raw and processed AEM data. This release also...

Natural cave passages penetrating a coastal aquifer in the Yucatan Peninsula (Mexico) were accessed to investigate how regional meteorology and hydrology control methane dynamics in karst subterranean estuaries. Three field trips were carried out in January 2015, June 2015, and January 2016 to obtain year-long high-resolution temporal records of water chemistry and environmental parameters below and above the surface at a site (Cenote Bang) within the Ox Bel Ha cave network. These efforts resulted in chemical records of dissolved methane concentrations and its stable carbon isotopic content and major ion concentrations (i.e., chloride and sulfate) in approximately 2.5-day resolution from January 2015 to January...
Natural cave passages penetrating coastal aquifers in the Yucatan Peninsula (Quintana Roo, Mexico) were accessed to investigate how regional meteorology and hydrology control dissolved organic carbon and methane dynamics in karst subterranean estuaries, the region of aquifers where fresh and saline waters mix. Three field trips were carried out in December 2013, August 2014, and January 2015 to obtain 1) physicochemical and 2) geochemical data from the water column and 3) temporal records of water chemistry and hydrological parameters below and above the surface at three sites within the Ox Bel Ha cave (Cenote Jailhouse, Cenote Naach Wennen Ha, and Cenote Odyssey) and another cave (Cenote Crustacea). These efforts...
