Holocene deglaciation work (WP1) includes: 1) ice sheet-ocean processes during the transition from a subglacial to a seasonal-open marine environment; and 2) develop a chronological context for ice sheet-ocean interactions and changing paleoenvironments. Results of WP1: sedimentological model for the Holocene deglaciation (~24kyr-9 kyr), characterized the spatial and temporal changes in the marine based EAIS, linking these changes in oceanographic conditions and biota adaptation. Results have been disseminated in congresses and are now in revision by authors to be submitted in an Open Access journal. Pliocene interglacials work (WP2) to characterize changing environmental and biota conditions during the terminations. Results of WP2 (in progress): characterize the different sedimentological, biological and geochemical (oceanic) conditions during Pliocene “warmer-than-present” terminations. We are able to characterize for the first time ocean and phytoplankton responses to changing conditions within each warm interval. First results were presented in a congress and will be published in an Open Access journal.
Participation in the Tasmandrake Spanish Powell2020 Antarctic cruise. Water samples were obtained to characterize physical-biochemical-ecosystem processes, key to calibrate the indicators in sediment cores used to interpret past environments. Publications are being prepared.
Most analyses have been conducted with the analytical techniques proposed in the project, despite of some analytical delays and secondment cancellations caused by the COVID-19:
A Data Management Plan was submitted on time, as deliverable, in November 2019; Analysis of CT-scan data with ImageJ/FIJI software; Microfossil analyses; Grain size, biogenic opal and smear slides samples at the IACT; HRSEM analysis at CIC-UGR; Grain size analysis at the University of Bordeaux and CIC; Interpretation/integration of all data at the IACT; Collaboration with national/ international laboratories include: University of Bordeaux (grain size), University Salamanca (diatoms), University of Wellington (ramped pyrolysis dating), ETH (laser dating), Stanford University (radiocarbon dating), University of Salamanca and CIC (UGR) (radiocarbon dating), and University of Bremen (Biogenic opal); Short visits to Universities of Bordeaux, Salamanca and IGME (Madrid) were done to work with collaborators; International congresses: three online due to COVID-19 (SCAR 2020, EGU 2021 and EGU 2022) and one in person in 2021 (SGE, Vitoria, Spain). Abstracts published in Open Access; Preparation of Open Access WP1 and WP2 publications; Reviewer for the Journal NHESS; Participation in IACT activities (e.g. virtual and in person project meetings, mentoring PhD students; preparation of expedition logistics, etc); Memberships: POLARCSIC, Academia Net: SNSF, ICEPRO (CSIC), EGU 2021/2022, and SCAR INSTANT; Outreach/educational activities: talks, workshops, blog in newspaper, radio, social media, and educational materials: co-author in a book chapter (CSIC editorial), videos, flyers, photo exhibition; Training courses: IMAGEJ/FIJI software, the Managing Biodiversity data online course in Polar region (2021) and Database ConCiencia (CSIC);Seminars and informative workshops: Tasmandrake (2019), Polar Committee (2019), ICEPRO (2021), Inquamare Workshop (2021), and PTI Polar CSIC (2022).
