Dunstaffnage Marine Laboratory: projects/activities

To edit or add records to any of the catalogs, log in or create an account.

Directory entires that have specified Dunstaffnage Marine Laboratory as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

1. Benthic processes in the Arabian Sea: mechanistic relationships between benthos, sediment biogeochemistry and organic matter cycling

1. To quantify benthic community parameters for all size classes of fauna across the Oxygen Minimum Zone (OMZ) 2. To make a detailed assessment across the OMZ of a) sediment accumulation, mixing and irrigation rates and depths and b) environmental factors acting as controls on faunal activity 3. To characterise solid phase and porewater geochemistry of sediments across the OMZ 4. To assess a) faunal digestive Organic Matter (OM) alteration, b) the relative importance of chemo- and photosynthetic food sources, and c) benthic food web structure, across the OMZ 5. To determine porewater profiles and benthic solute fluxes in situ, and to assess faunal OM assimilation and trophic relationships by monitoring tracers during shipboard and in situ incubations 6. To obtain high resolution porewater profiles of oxygen and other key analytes, free of pressure and other effects potentially introduced by core recovery 7. To determine in situ oxygen consumption rates and benthic fluxes 8. To use labelled tracers to assess mixing and irrigation rates, faunal OM assimilation, and size-selective ingestion and mixing 9.To determine sediment denitrification and sulfate reduction rates and their contributions to OM remineralisation

2. Late Holocene and Shallow Marine Environments of Europe (HOLSMEER)

1. To generate high-resolution quantitative palaeoceanographic/palaeoclimatic data from NE Atlantic coastal/shelf sites for the last 2000 years using a multidisciplinary approach 2. To develop novel palaeoclimatic tools for shallow marine settings by (i) calibrating the proxy data against instrumental datasets, (ii) contributing to transfer function development, and (iii) then to extrapolate back beyond the timescale of the instrumental data using the palaeoclimate record 3. To investigate the link between late Holocene climate variability detected in the shelf/coastal regions of western Europe and the variability of the oceanic heat flux associated with the North Atlantic thermohaline circulation, and to compare such variability with existing high-resolution terrestrial proxies to help determine forcing mechanisms behind such climate change 4. To lay a foundation for the identification of hazards and resources linked with, or forced by, such climate change.
