USGS Lake Erie East Harbor bottom trawl data series, 1961-2011 (ver. 2.0, March 2020)

The USGS Lake Erie Biological Station’s East Harbor sampling program began in 1961 with the commissioning of the research vessel Musky II. It is the longest known continuous trawl survey in Lake Erie.  In addition to spanning over 50 years, the data series is unique for three prominent design elements: 1) sampling was conducted at three depth strata; 2) replicate trawl samples were collected at each depth stratum; and 3) sampling was conducted during both day and night. Unlike other trawl series collected in Lake Erie, and throughout the Great Lakes, the East Harbor program is the only one to combine these sampling practices in a single survey.  
In 2012, the original vessel used since the inception of the East Harbor program, the research vessel Musky II, was retired and replaced with a larger research vessel, Muskie. The change in vessel necessitated change in the trawl net and all of the rigging and hardware needed to tow it (LEBS, 2013; cross-referenced below). This effectively ended the time series of data, which were collected with the exact same vessel and sampling gear for 51 years. This historical data set has proven valuable for testing hypotheses about long-term ecological change and the impacts of non-native species invasions in the Great Lakes.  Further, at various times through history it provided accurate predictions of recruitment for species, such as Yellow Perch, that support some of the most valuable fisheries in the Great Lakes. For future scientific endeavors, and to ensure this work is available to the public, we present here the entire data set from 1961 through 2011.
This is an updated data release. For revision information, reference the “Version history” text file or the process steps in the metadata record.

Pore water chemistry of wetlands in Interior and Southcentral Alaska, 2015 and 2016

The pore water of eight wetlands in Interior and Southcentral Alaska were collected in 2015 (17 July – 22 July) and 2016 (12 July – 16 July). Wetlands were selected to span a range in trophic status (e.g., from bog to fen). Using ultraclean trace metal clean protocols, pore waters were sampled from shallow (10‑15 cm) and deep (20-35 cm) depths below the water table. Field measurements reported for pore waters include temperature, specific conductance, pH, dissolved oxygen (DO) concentration, and oxidation-reduction potential (ORP). Pore waters were filtered on site and measured in-lab for major cations, inorganic anions, simple organic acids, inorganic sulfide, iron oxidation state, dissolved organic carbon (DOC), ultraviolet and visible light (UV-Vis) absorption, dissolved organic matter (DOM) fluorescence, electron release from DOM and iron(II), total mercury (HgT), and methylmercury (MeHg). Unfiltered pore water was collected for quantification of dissolved gaseous mercury (Hg(0)(aq)). 
Major cation concentrations (calcium, magnesium, manganese, iron, sodium) were determined by inductively coupled plasma-optical emission spectrometry (ICP-OES). Inorganic anion concentrations (chloride, nitrate, sulfate) and simple organic acid concentrations (acetate, formate, butyrate, propanoate, oxalate) were determined by ion chromatography (IC). Inorganic sulfide was measured by ion selective electrode. The distribution of iron oxidation state was determined using a spectrophotometric assay. DOC concentration was quantified by wet-oxidation. Ultraviolet (UV) absorbance at the wavelength of 254 nanometers was measured by UV-Vis spectrophotometry. Iron(III) absorbs UV light at 254 nanometers and, if present at appreciable concentration, can influence UV absorbance values. Therefore, UV absorbance values at 254 nanometers were corrected for the influence of iron(III). Specific UV Absorbance (SUVA) at 254 nanometers is a calculated parameter that correlates with the percent aromatic carbon of the DOM.  SUVA at 254 nanometers was calculated using values of UV absorbance at a wavelength of 254 nanometers corrected for iron(III) interference. The DOM fluorescence index was measured and is a proxy for DOM source material. The release of electrons from DOM and iron(II) was measured in the field using a colorimetric assay. HgT, MeHg, and Hg(0)(aq) concentrations were quantified and used to calculate the concentration of inorganic divalent mercury (Hg(II)i).

Morphological data for description of a new species of carangiform fish of the genus Trachinotus from the Indo-West Pacific

The dataset is a composite of morphological data used in the description of a new species of marine fish, Trachinotus macrospilus (Teleostei: Carangidae), endemic to the Marquesas Islands of the Indo-West Pacific. In the addition to the newly described species,  three previously named (nominate) species of the same genus are compared and redescribed in this same manuscript. The morphological data include both mensural (morphometric) and meristic (count) data. Synonymies are provided for all species, since many misidentifications have been made in the literature, which dates to the early 1800's.

Geochemistry data for the USGS Gulf Coast #1 West Woodway core - A thermally immature core of the Eagle Ford Group in central Texas (ver. 1.1, April 2025)

Petroleum source rocks deposited during Cenomanian – Turonian time (late Cretaceous) are major generators of continuous and conventional oil and gas resources in the Gulf of Mexico Basin. The Eagle Ford Shale is a particularly important petroleum system and represents a substantial fraction of total oil and gas production in the United States. Significant lateral and vertical geochemical and mineralogical variability has been identified in previous studies of the Eagle Ford Shale, but most recent work has focused on the area of the play southwest of the San Marcos Arch. As part of a larger USGS coring program to examine important continuous oil and gas plays in the Texas-Gulf Coast region, the USGS Gulf Coast Petroleum Systems project drilled a core hole in a thermally immature near Waco, TX that recovered the Pepper Shale and the upper and lower Eagle Ford shale intervals (Eagle Ford Group). A combination of bulk organic and inorganic geochemistry and mineralogy along with molecular and isotopic analyses of rock extracts are presented and accompany a manuscript (French and others, 2019) that discusses organic matter source variability and depositional environment, as well as examining drivers of organic enrichment.
Although a recent assessment of petroleum resources in southwest Texas associated with the Eagle Ford Shale was completed in 2018, many questions remain regarding the distribution of source rock organic facies and the nature of the Eagle Ford as an indigenous-continuous petroleum system, especially north of the San Marcos Arch. Ongoing research into these and other issues is vital for refining and updating geologic models for future assessments of these strata and also as a potential analog for other similar petroleum systems in the U.S. and around the world.
This data set includes two spreadsheets.  The first outlines the individual samples collected during the drilling activity. The second provides results from analyses performed and are grouped into High and Low resolution.  Documentation on the methodology and the attributes are discussed in the entity and attribute section

Produced water chemistry data collected from the Orcutt Oil Field, 2018, Santa Barbara County, California

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water and casing gas samples from oil wells and injectate stored in surficial tanks planned for underground injection in the Orcutt Oil Field in Santa Barbara County in 2018. Samples were collected from the Orcutt Oil Field on February 6th and February 7th, 2018. This digital dataset contains the site information, analyzing laboratories and methods, and water and gas chemistry and quality-control results for these samples. Chemistry results include concentrations of dissolved noble and hydrocarbon gases and their isotopic composition; concentrations of inorganic constituents including salinity, major and minor ions, trace elements, and nutrients; low molecular weight organic acids; dissolved organic carbon and optical properties of dissolved organic carbon; stable isotopes of water, strontium dissolved in water, and carbon in dissolved inorganic carbon; and radium isotopes. Samples were analyzed in the field and by eight laboratories operated or contracted by the USGS.
