... Abstract: TEMPERSEA is a gridded temperature product for the Red Sea covering in the period 1958-2017 at monthly resolution. The product covers the Red Sea and the Gulf of Aden with a spatial resolution of 0.25°x 0.25° and 23 vertical levels. This product is based on a large number of in-situ observations collected in the region. After a specific quality control, a mapping algorithm has been applied to homogenize the data. Also, an estimate of the accuracy of the product has been generated to accurately define the uncertainties of the product.

... Abstract: The datasets were acquired to estimate whole stream metabolism (photosynthesis, respiration). Photosynthetic active radiation, atmospheric pressure, stream water discharge, water temperature and dissolved oxygen concentrations were recorded at five-minute time intervals at six stations (three stream reaches) along two parallel first order streams: Cairn Burn (May 2007-July 2008) and Birnie Burn (May 2007-October 2007). In addition, stream reach parameters necessary to calculate mean travel time, oxygen reaeration coefficient and proportion of base flow under varying discharge are given with their uncertainties. The forms of the equations to calculate mean travel time τ [min], oxygen reaeration coefficient k2 [/min] and proportion of base flow p(Q_b) [range 0 to 1] are: τ=a*Q^b k2=a*Q+b p(Q_b)=1/(1+exp(a*ln(Q)-b)) with discharge Q [l/s] taken as Q_ECN for Birnie Burn and Q_C1 for Cairn Burn. The discharge for stations upstream of the calibrated flumes were also calculated after corrections for lateral inflows determined by tracer studies. The streams undercut the banks so two stream widths were given: wetted stream bed width (recommended to use in stream metabolism calculations) and open width (recommended to calculate amount of light available to stream bed). Stream reach length is also given. Category: geoscientificInformation Source: Not Available Supplemental Information: Not Availble Coverage: Not Available

... Abstract: These data are in association with a study conducted in the Santa Barbara Basin, California, USA that were used to develop a 20th century record of ocean acidification in the California Current Ecosystem. These data are based on the planktonic foraminifera species G. bulloides' shell characteristics, specifically area-normalized shell weight (ANSW) and include both core sample population average values and the individual data used to calculate sample averages. Additional information on collection of ANSW data can be obtained in Osborne et al., (2016) publication in Paleoceanography (doi:10.1002/2016PA002933). Carbonate system calculations for the downcore record determined based on the proxy CO32- values using the CO2SYS program are also included in this archive. Stable isotope geochemistry data measured by IRMS for individuals used in the ANSW and two additional study species (N. dutertrei) and N. incompta) are also included. Core radioisotope geochemistry data used to develop an age core for the multi-core record are included in this archive.

... Abstract: The shapefile contains 354 polygons which are boundaries of retrogressive thaw slumps (RTSs) and other land covers (non-RTS) in Beiluhe on the Tibetan Plateau for training a deep learning algorithm (DeepLabv3+). Among them, 264 are RTS boundaries delineated on Planet images acquired in May 2018, 90 of them are non-RTS polygons. In the attribute table of the shapefile, "class_int" equal to "1" means an RTS polygon and "0" for a non-RTS polygon.

... Abstract: This work provides a global dataset on the fate of land evaporation for a fine-meshed grid of source and receptor cells. The dataset was created through a global run of the numerical moisture tracking model WAM-2layers. The tracking was conducted on a 1.5° * 1.5° grid and was based on reanalysis data from the ERA-Interim database. Climatic input data were incorporated in 3 respectively 6-hour time steps and represent the time period from 2001 to 2018. The tracking direction was forwards in time and the geographical borders of the model were located at +/- 79.5° latitude. As a result of the model run, the annual as well as the monthly average fate of evaporation was determined for 8684 land grid cells (all land cells except those located within Greenland and Antarctica) and provided via source-receptor matrices. The gained dataset was complemented via an aggregation to country and basin scales in order to highlight possible usages for areas of interest larger than grid cells. This resulted in data for 265 countries and 8223 basins. Finally, five types of source-receptor matrices for average moisture transfers were chosen to build the core of the dataset: land grid cell to grid cell, country to grid cell, basin to grid cell, country to country, basin to basin. Besides providing results averaged over the considered period (basic dataset), inter-annual results on a grid cell basis (inter-annual dataset) were added in addition. The dataset is the first ready-to-download dataset providing the overall fate of evaporation for land-cells of a global fine-meshed grid in monthly resolution. At the same time, information on the sources of precipitation can be extracted from it. It could be used for investigations into average annual, seasonal and inter-annual sink and source regions of atmospheric moisture from land masses for most of the regions in the world and comes along with example scripts for the readout and plotting of the data.

... Abstract: The drainage divides of ice sheets separate the overall glaciated area into multiple sectors. These drainage basins are essential for partitioning mass changes of the ice sheet, as they specify the area over which basin specific measurements are integrated. The delineation of drainage basins on ice sheets is challenging due to their gentle slopes accompanied by local terrain disturbances and complex patterns of ice movement. Until now, in Greenland the basins have been mostly delineated along the major ice divides, which results in large drainage sectors containing multiple outlet glaciers. However, when focusing on measuring glaciological parameters of individual outlet glaciers, more detailed drainage basin delineations are needed. Here we present for the first time a detailed and fully traceable approach that combines ice sheet wide velocity measurements by Sentinel-1 and the high resolution TanDEM-X global DEM to derive individual glacier drainage basins. We delineated catchments for the Northeast Greenland Ice Sheet with a modified watershed algorithm and present results for 31 drainage basins. Even though validation of drainage basins remains a difficult task, we estimated basin probabilities from Monte-Carlo experiments and applied the method to a variety of different ice velocity and DEM datasets finding discrepancies of up to 16% in the extent of catchment areas. The proposed approach has the potential to produce drainage areas for the entirety of the Greenland and Antarctic ice sheets.
