title: Strength measurement of bulk sediment from the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

description: This dataset contains strength measurements of bulk sediment on the ends of whole round core samples including hand vane (sample code VANE), pocket penetrometer (sample code PEN), and fall cone and laboratory table vane measurements (sample code TBVN). Onboard the Helix Q4000, a handheld vane shear and a pocket penetrometer were used to estimate the undrained shear strength. Measurements were made rapidly, typically within 1 hour of cutting core sections. In Salt Lake City, measurements of strength were performed with a fall cone penetrometer and an automated table vane shear device. Both devices were mounted on top of the table frame. Core sections were positioned vertically on an adjustable platform and secured with a vice grip. See Expedition UT-GOM2-2 Methods: Undrained Shear Strength (Flemings et al., 2025a, https://doi.org/10.5281/zenodo.13971228).

Additional data you might expect to find in this dataset can instead be found at the following locations:

Most raw hand vane and pocket penetrometer measurements can be found in scans of the handwritten core curation sheets from the Helix Q4000 in the conventional coring dataset (https://doi.org/10.5281/zenodo.14518080).  Three measurements were made in Salt Lake City and the raw data file is below, PocketPen_HandVane_SLC_handwritten_log.pdf.

Measurement depths can be found in the curation dataset (http://doi.org/10.5281/zenodo.14926309). Download the file UT-GOM2-2 CORE LOG depths – sortable.xlsx. See tab “Sample-measurement log”, measurement codes “VANE” for hand vane, “PEN” for pocket penetrometer, and “TBVN” for table vane and fall cone measurement depths. Some voids were consolidated by moving sediment within the core liner in College Station and sediment depths in section (and resulting mbsf) were changed in the electronic log (See Expedition UT-GOM2-2 Methods: Consolidation of Voids (Flemings et al., 2025a)). Therefore, the depth in section of the VANE and PEN measurements in the electronic log may differ from the depth in the handwritten logs from the Helix Q4000 found in the conventional coring dataset (https://doi.org/10.5281/zenodo.14518080).

title: Void gas molecular composition (C1-C5 hydrocarbon, CO2, and air) from the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

description: This dataset contains gas composition data from void gas samples (sample code VG). Void gases were extracted using a stainless-steel puncture sampler that was pushed through the core liner shortly after the core was collected onboard the Helix Q4000. Samples were analyzed onboard the Helix Q4000 using an Inficon Fusion MicroGC chromatograph with molecular sieve, PLOT Q columns, and thermal conductivity detector. Carbon dioxide, methane, ethane, propane, butane, isobutane, and pentane were measured.

title: Particle size distribution (grain size) of discrete sediment samples from the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

description: This dataset contains particle size distribution assessed using two methods. Discrete samples from split cores (sample code GSL) were measured using a Malvern Mastersizer 3000 particle size analyzer with a Hydro LV dispersion unit. Larger samples (sample code MAD blended material) subsampled from Moisture and Density whole rounds (sample code MDW) were measured using a specific gravity hydrometer in conformance with ASTM D7928. A geoscientific and a geotechnical classification were used to name the sediments.

title: Quantitative Degassing of pressure core sections from the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

description: This dataset contains quantitative measurements of the volume of gas and liquid produced during the stepwise depressurization of pressure core whole round sections to atmospheric pressure (quantitative degassing, core processing code QD). These volumes were used to calculate dissolved methane concentration and hydrate saturation. Pressure cores were cut in PCATS and transferred to pressure core chambers. These chambers were depressurized slowly while produced gas and water volumes were tracked over the course of dissociation, and the gas composition was analyzed. The pressure before and after each step was noted. The total amount of gas produced and remaining in the chamber were used to calculate the dissolved methane concentration and gas hydrate saturation. See Expedition UT-GOM2-2 Methods: Quantitative Degassing (Flemings et al., 2025a, https://doi.org/10.5281/zenodo.13971228)

description: This dataset includes Temperature Dual Pressure Penetrometer (T2P) water column test data.

The penetrometer is lowered downhole on a wireline, driven into the sediment formation, and left in-place while measuring the dissipation of temperature and pressure.

title: Calcareous Nannofossil Biostratigraphy from the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

description: These data include calcareous nannofossil abundance data collected on paleontology samples (sample code PAL). Specimens were examined and documented via photomicroscopy in a transmitted light microscope. A modified version of Styzen's (1997) quantitative counting method of calcareous nannofossils was applied to each sample examined ensuring precise interpretation of the age and assemblage. Biostratigraphic events, such as First and Last Appearance Datums (FAD and LAD), were determined, and known ages for these datums were plotted by depth.

title: Elemental composition of intertidal shellfish sandbanks sediment samples within Ría de Arousa, Spain

description: The GEOMA Research group from the University of Vigo implements a solution to improve the knowledge of the sediment dynamics, the stability of the ecosystem substratum, and its response to the predicted Climate Change outcome (INTERM). The INTERM solution is based on sedimentological monitoring of sandbanks at specific locations of clam exploitation in the Ría de Arousa (Pontevedra, Spain).

 Here we show the results of X-ray Fluorescence analysis carried out on the bulk fraction of sediment samples collected in five locations with current (Camaxe, Xastelas, O Sarrido, and O Bohido) or stopped (Lombos de Ulla) shellfish activity. The analyses were conducted at the CACTI facilities (Uvigo) using an X-ray Fluorescence Spectrometer by Wave Scattering (Siemens SRS3000).

This study is part of the “Accelerating and upscaling transformational adaptation in Europe: demonstration of water-related innovation packages (TRANSFORMAR)” coordinated by the Universiteit Antwerpen and funded by the European Union’s Horizon program (H2020_101036683).
