PurposeResearch
ObjectivesAMT25: The overall aim of the Atlantic Meridional Transect programme is: to quantify key biogeochemical and ecosystem processes and their inherent variability over extended time and spatial scales in the Atlantic Ocean. This is achieved by executing an annually repeated meridional transect through contrasting oceanic provinces, ranging from oligotrophic deserts, to highly productive shelf seas.

Specific objectives:
- To quantify the nature and causes of ecological and biogeochemical variability in planktonic ecosystems;
- To quantify the effects of this variability on nutrient cycling, on biogenic export and on air-sea exchange of climate active gases;
- To construct multi-decadal, multidisciplinary ocean time-series which are integrated within a wider "Pole-to-pole" observatory concept;
- To provide essential sea-truth validation for current and next generation satellite missions;
- To provide essential data for global ecosystem model development and validation;
- To provide a valuable, highly sought after and unique training arena for the next generation of UK and international oceanographers.

JR864: The oceanographic research ship RRS James Clark Ross attempted to physically and biologically characterise Ascension Island's shelf from 14th-18th October 2015. Multibeam sonar swath was used to generate the first open-access, high resolution mapping of Ascension Island's seabed between 100-1100m depth. These data was used to determine seabed profile and rugosity characteristics. Seabed substratum was investigated using a benthic camera lander (SUCS) and water column physico-chemistry was gained using CTD. The SUCS provided 500 photographs and video clips of benthos from 21 site/depth combinations, which showed a wide disparity in richness and density of biodiversity. These were ground-truthed by targeted Agassiz trawl samples to collect vouchers specimens for morphological and genetic identification. Specimens collected were photographed, fixed and then preserved in 96% ethanol for later genetic analyses. Preliminary analysis of the biodiversity captured was undertaken in the Conservation Department building, Georgetown, Ascension Island and indicated new records for the Island including first records of brachipods.
