title: Rapid Stress Cycling using a Modified Split Hopkinson Pressure Bar Approach Experimental Data

description: We investigate the effect of rapid stress cycling on the dynamic compressive strength of Westerly Granite using a modified Split Hopkinson Pressure Bar approach. With this approach, generated load paths are composed of two distinct stress cycles separated a brief (hundreds of microseconds) dwell time. Under these loading conditions, the strength and critical strain rate thresholds required to pulverize samples can be reduced by a factor of two when compared with those required in traditional high strain rate tests with the Split Hopkinson Pressure Bar. These results suggest traditional experimental approaches may overestimate material strength when complex load paths are involved. Braunagel_ds01.xlsx and Braunagel_ds02.xlsx contain the voltage time series for the tests described in the above study. Braunagel_ds01.xlsx contains the raw time series of experiments conducted prior to installation of a Shimadzu Hypervision HPV-2 high-speed camera system and Braunagel_ds02.xlsx contains the time series of experiments following camera installation. The first worksheet in each file describes the format of each of the following datasets (contained in subsequent worksheets). Braunagel_Mechanical_Results.xlsx contains the interpreted mechanical data and the assigned post-mortem damage state for each sample. Avi. files contain the high speed camera videos of sample deformation during each test contained in Braunagel_02.xlsx. The number in the lower right corner of each frame is the time since recording began in microseconds. Sample name corresponding to each video is indicated in the file name.

title: Reanalysis of vertical mixing in mesocosm experiments: PeECE III and KOSMOS 2013

description: Here we provide optimised vertical eddy diffusivity estimates for the PeECE III and KOSMOS 2013 mesocosm experiment, obtained from a model-based reanalysis. These diffusivities are derived from the observed temperature and salinity profiles that have been published in Schulz et al., 2008.Furthermore, we make our model code available, providing an adjustable tool to simulate vertical mixing in any other pelagic mesocosm.We also provide the interpolated and regridded temperature and salinity profiles of the PeECE III experiment as well as the density profiles which we calculated from the temperature and salinity profiles using the R package seacarb (Lavigne et al., 2011). These data files are required as input to run simulations of the PeECE III experiment with the 1D mesocosm mixing model.The columns of the environmental files (required input files for the model) from left to right are: Experiment year, month, day, Julian day, photosynthetically active radiation (PAR) [W/m^2], temperature [C], salinity [PSU], CO2 concentration [ppm], wind speed [m/s]. The rows list the respective value of each hour of the experiment. Temperature and salinity in this table are hourly interpolated values of the daily measurements published by the PeECE III team (2005). PAR has been calculated from global radiation data of Bergen provided by Olseth et al., 2005.In the temperature, salinity and density files, the rows indicate the depth (0.5 m resolution, the first row is the surface, the last row is the bottom), whereas the columns indicate the experiment time at an hourly resolution.

title: Marine Bioregions for coastal subtidal shallow rocky reef of the Galapagos Archipelago, GIS layer for Edgar et al. 2004

description: The Galapagos coastal area is the most studied of the Galapagos Marine Reserve (GMR) and also the most vulnerable to impacts since it is where the greatest part of human activities takes place (fishing, tourism, leisure, etc.). Edgar et al. (2004) analysed shallow subtidal rocky reef coastal biodiversity data (fish and macro-invertebrate communities) collected in 2000-2001 in order to derive regional biogeography areas. Sampling units consisted of 50 m x 10 m line transects for fish and 50 m x 2 m line transects for macro-invertebrate species (sea cucumbers, sea urchins, octopus, lobsters, large gastropods, etc.) at various depths between - 2 and - 20 m and distributed along the coastal subtidal area of 50 islands and islets of the Galapagos. A multivariate analysis of the data resulted in the identification of three major biogeographical regions: the Far-northern islands of Darwin and Wolf; the Central-south-eastern islands, including the east coast of Isabela; and the Western region, comprising Fernandina and the west coast of Isabela. The Central-south-eastern region could be further divided in two, namely the Northern region, including the islands of Pinta, Marchena and Genovesa; and the Central-south-eastern region, including the islands of Santiago, Rábida, Pinzón, Santa Cruz, Baltra, Santa Fe, San Cristóbal, Floreana, Española and the eastern side of Isabela. Another region could be further identified in the Western region, the Elizabeth region, covering an area comprising the Bolivar channel and Urbina and Elizabeth bays down to Punta Moreno in Isabela and Punta Mangle in Fernandina. Edgar et al.'s study is one of the most cited marine studies in the Galapagos. However, the authors only included a small scale map and a written description of the bioregions geographical limits within the GMR but did not include a detailed paper or digital map. Here, I provide an interpretation of the bioregions identified in Edgar et al.'s study based on the figure and the descriptions included in it. The resulting data set is a GIS layer in ArcGIS shapefile format, EPSG 32715 (WGS 1984/UTM Zone 15S) and a Google Earth layer in KMZ format of the GMR shallow subtidal rocky reef bioregions based on fish and macro-invertebrate data. The layers include attribute information on bioregion name and area (in square km). This dataset will be of most utility to those attempting to use Edgar et al.'s Galapagos bioregions in their analyses since it provides for a consistent use of bioregion boundaries.Reference: Edgar, G.

title: (Table 1) Clay minerals at DSDP Hole 93-603B

description: Cretaceous sediments encountered in Hole 603B contain a 17 Å smectite as the principal clay mineral, with lesser amounts of illite, kaolinite, and randomly interstratified illite/smectite (I/S). No evidence of smectite to I/S transformation with depth is seen in the interval between 1040 and 1570 m below the sediment surface. Although the presence of some volcanic ash suggests a volcanic origin for the smectite, the nature of associated organic matter together with prevailing sedimentological models for Cretaceous sedimentation on the lower continental rise argue more strongly for a dominantly terrestrial origin for the clays.

title: Observation of a high abundance aggregation of the deep-sea urchin Chaetodiadema pallidum A. Agassiz and H.L. Clark, 1907 on the Northwestern Hawaiian Island Mokumanamana

description: AUV images of deep-sea megafauna on the seamount Mokumanamana in the Northwestern Hawaiian Islands revealed a large aggregation of the diadematoid urchin Chaetodiadema pallidum. This species had not been previously recorded on this seamount, but was known from other locations in the Hawaiian Archipelago. A total of 11,360 individuals were counted by eye from 1,369 seafloor images along the 200, 250, and 300 m depth contours on the west side of Mokumanamana. To estimate the full population size, Inverse Distance Weighting and Empirical Bayesian Kriging interpolation calculated a total population size of between 139,552 and 144,063 individuals. These estimates are 1-2 orders of magnitude greater than any previous estimates of urchin aggregation abundances. Little biological data exists for this species; thus, it is difficult to know if this is a spawning aggregation, a feeding front, a type of "schooling" behavior, or some combination thereof, but a food source did seem to be present in the form of mesophotic green algal detritus.

title: Data for Effect of Mesoscale Oceanic Eddies on Extratropical Cyclogenesis: a Tracking Approach

description: Oceanic eddies populated in the western boundary current regions in the midlatitude, have been found to exert significant influence on atmospheric boundary layer, storm tracks as well as largescale atmospheric circulation. However, mechanisms governing how mesoscale sea surface temperature (SST) anomalies associated with oceanic eddies affect extratropical cyclogenesis remains unclear. Here, we investigate the influence of Kuroshio oceanic eddies on cyclogenesis in the North Pacific in high resolution climate model simulations using a cyclone tracking approach. Based on cyclone tracking and composite analyses, we find that presence of mesoscale SST anomalies almost doubles water vapor supply, leading to significant increase of diabatic heating release and eddy potential energy (EPE) to eddy kinetic energy (EKE) conversion and thus supporting stronger storm growth rate and intensified cyclones.

title: Clumped isotope measurements of Middle to Late Jurassic belemnites and ammonites from the Subboreal Province, link to analysis sheet

description: Here, we provide the results of the clumped isotope analyses of 24 biogenic carbonate samples, along with the results of carbonate reference materials (ETH1–4, Carrara, MuStd, Strauss) and equilibrated gases (25 °C and 1000 °C). Carbonate digestion at 90 °C and subsequent CO2 purification was done on an automated line connected to a ThermoFisher MAT 253 isotope ratio mass spectrometer. We present the raw isotope values calculated using both the [Gonfiantini/Santrock] and the [Brand]/IUPAC isotopic parameters. The raw data is projected onto the carbon dioxide equilibrium scale using the equilibrated gases and without applying any fractionation factor to the final values. Preparation methods and mass spectrometry analytics are further detailed in the associated files and the linked article.

title: Properties of seawater from a Sea-Bird TSG temperature and conductivity sensor mounted on the continuous surface water sampling system during campaign TARA_20091214Z of the Tara Oceans expedition 2009-2013

description: The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data publication contains measurements from the Continuous Surface Sampling System [CSSS] made during one campaign of the Tara Oceans Expedition. Water was pumped at the front of the vessel from ~2m depth, then de-bubbled and circulated to a Sea-Bird TSG temperature and conductivity sensor. System maintenance (instrument cleaning, flushing) was done approximately once a week and in port between successive legs. All data were stamped with a GPS.
