JRAP #4 (hydrography)
4D characterization of trans-boundary hydrography and transport
Lead: AZTI (Anna Rubio)
The JRAP#4 aims to contribute to assess the following MFSD descriptors:
Mainly D7 (Permanent alteration of hydrographical conditions). JRAP#4 will allow for the continuous monitoring of hydrographic conditions. This will permit to assess if any alteration of the hydrographical conditions (e.g. due to climate change) is affecting the ecosystem.
D10 (Properties and quantities of marine litter): Marine litter is advected or drifted by marine currents. JRAP#4 will provide information about hydrodynamics and derived transport to infer the spatial distribution (e.g. convergence areas and coastal arrivals) of this not-desirable material.
D2 (Non-indigenous species introduced by human activities): Ocean changes (e.g. ocean warming) induced by the climate change (partly induced by human activities) could be the reason of the arrival of non-indigenous species (including gelatinous organisms such as the Portuguese man-of-war Physalia physalis), which have low swimming abilities and whose spatial distribution is thus also highly depending on hydrodynamics JRAP#4 will also provide inputs for other JRAPs, which will be focused on other descriptors/ this is especially the case of JRAP#1, which is dealing with pelagic biodiversity and will require information about hydrographical and hydrodynamical conditions and spatiotemporal changes.
Involved JERICO Infrastructure
Coastal profilers with MASTODON moorings (thermistors), Gliders, offshore buoys, HF radars, gliders and underwater imaging systems (ecosystem monitoring).
Work plan and specific links with other WPs showing JERICO added value
The scientific strategy outlined in the task 1.1 (WP1) about the trans-boundary hydrography and transport topic will constitute the framework for JRAP#4. Results of task 2.3 (WP2) about harmonization and best practices for new systems (e.g. HFR), as well as developments on pelagic biodiversity (task 3.1: e.g. Underwater imaging systems), currents (task 3.2: e.g. HFR) and coastal profilers observations (task 3.3: e.g. MASTODOM) and finally the methodologies of sampling strategy improvement (task 3.7: 4D data assimilation-HFR observation design) will be applied. JRAP# 4 is organized in 3 stages listed hereafter.
JRAP#4.2 (M10-M23): On site implementation with deployment and recovery of complementary moorings (upgraded MASTODON, link with task 3.3), HF radar new antenna (link with task 3.2) and drifters. The new complementary data will be used to track high frequency variability of hydrology (below around 10 m depth) over the transboundary shelf/slope areas. The collection of jellyfish and marine litter data of surface transport for the study period and data processing according to the interoperability guidelines and QC standards developed in WP5.
JRAP#4.3 (M24-M36): Joint data analysis over the 3 study areas and transfer to virtual access service (WP6), results synthesis and publication to WP8: Individual platform data analysis; links between platforms; links between eulerian and lagrangian information; links between surface and water column data; validation with indicators; computing of the transport.
Expected results (outcomes to other WPs)
JRAP#4 results will return to task 1.6, and will provide information about gaps, overlaps and, in general, any improvement that should lead to recommendation of improved network of coastal observatories. Data at different processing levels will be available for the scientific community and stakeholders, taking into account both WP5 and main European channels (EMODnet and EuroGOOS, Copernicus, Coriolis, Seadatanet) requirements. Results will be presented in symposia, JERICO-NEXT website and websites belonging to the involved institutions and published in peer-reviewed scientific journals. They will contribute to the ocean literacy H2020 program.
Proposed deliverables are cross-cutting the 6 JRAPs, they intend to report the progress status and results during the whole duration of WP4.
D4.1 will report the topical scientific strategy of each JRAP, according to discussions and interaction with task 1.2 of WP1. (Month 9)
D4.3 will report progress following JRAP’s implementation. A specific attention will be paid to insure the data flows following the European channels according to standardization procedures set up in WP5.(Month 24).
D4.5 will report the final results, to valorise JERICO added value. It will also include a prospective chapter to propose monitoring and study strategies for future for each of the 6 topics. This will partly feed the task 1.6 (Month 43).
