    The Iso2k database: a global compilation of paleo-δ18O and δ2H records to aid understanding of Common Era climate (2020)

    Description: Reconstructions of global hydroclimate during the Common Era (CE; the past ∼2000 years) are important for providing context for current and future global environmental change. Stable isotope ratios in water are quantitative indicators of hydroclimate on regional to global scales, and these signals are encoded in a wide range of natural geologic archives. Here we present the Iso2k database, a global compilation of previously published datasets from a variety of natural archives that record the stable oxygen (δ18O) or hydrogen (δ2H) isotopic compositions of environmental waters, which reflect hydroclimate changes over the CE. The Iso2k database contains 759 isotope records from the terrestrial and marine realms, including glacier and ground ice (210); speleothems (68); corals, sclerosponges, and mollusks (143); wood (81); lake sediments and other terrestrial sediments (e.g., loess) (158); and marine sediments (99). Individual datasets have temporal resolutions ranging from sub-annual to centennial and include chronological data where available. A fundamental feature of the database is its comprehensive metadata, which will assist both experts and nonexperts in the interpretation of each record and in data synthesis. Key metadata fields have standardized vocabularies to facilitate comparisons across diverse archives and with climate-model-simulated fields. This is the first global-scale collection of water isotope proxy records from multiple types of geological and biological archives. It is suitable for evaluating hydroclimate processes through time and space using large-scale synthesis, model–data intercomparison and (paleo)data assimilation. The Iso2k database is available for download at https://doi.org/10.25921/57j8-vs18 (Konecky and McKay, 2020) and is also accessible via the NOAA/WDS Paleo Data landing page: https://www.ncdc.noaa.gov/paleo/study/29593 (last access: 30 July 2020).

    Marine Ecosystems of the North Pacific Ocean 2009–2016: Synthesis Report (2021)
    North Pacific Marine Science Organization (PICES) | Sidney, BC, Canada
    Details
    Publication Date: 2021-11-15
    Description: The PICES report on marine ecosystems is intended to periodically review and summarize the status and trends of the marine ecosystems in the North Pacific, and to consider the factors that are causing or are expected to cause change in the near future. This third North Pacific Ecosystem Status Report (NPESR3) focuses on the time period 2009–2016, and is a Synthesis Report which summarizes the ecosystem status for the entire North Pacific, and includes ecosystem updates for the 14 PICES biogeographical regions in the North Pacific, and information on climate and human dimensions. PICES Ecosystem Status Reports provide an important record of our understanding of conditions in the North Pacific for the specific time periods of interest. Ecosystem conditions are quickly changing, and the volume of data being collected is ever-increasing. These PICES Ecosystem Status Synthesis reports continue to advance scientific knowledge about the ocean environment and climate change, living resources and their ecosystems, and the impacts of human activities.

    Geothermal heat flow in Antarctica: current and future directions (2020)
    Copernicus
    In:  EPIC3The Cryosphere, Copernicus, 14(11), pp. 3843-3873, ISSN: 1994-0424

    Description: Antarctic geothermal heat flow (GHF) affects the temperature of the ice sheet, determining its ability to slide and internally deform, as well as the behaviour of the continental crust. However, GHF remains poorly constrained, with few and sparse local, borehole-derived estimates and large discrepancies in the magnitude and distribution of existing continent-scale estimates from geophysical models. We review the methods to estimate GHF, discussing the strengths and limitations of each approach; compile borehole and probe-derived estimates from measured temperature profiles; and recommend the following future directions. (1) Obtain more borehole-derived estimates from the subglacial bedrock and englacial temperature profiles. (2) Estimate GHF from inverse glaciological modelling, constrained by evidence for basal melting and englacial temperatures (e.g. using microwave emissivity). (3) Revise geophysically derived GHF estimates using a combination of Curie depth, seismic, and thermal isostasy models. (4) Integrate in these geophysical approaches a more accurate model of the structure and distribution of heat production elements within the crust and considering heterogeneities in the underlying mantle. (5) Continue international interdisciplinary communication and data access.
