Cruise Inventory Information

Long name RRS James Clark Ross (74JC) cruise JR20130713 (JR288)
Short name JR20130713 (JR288)
Objectives and Narrative The cruise took place as part of the larger NERC funded consortium project called Aerosol-Cloud Coupling And Climate Interactions in the Arctic (ACCACIA). The overarching objective of the project is to reduce uncertainty in the representation of Arctic cloud and aerosol processes in climate models. Airborne measurements of aerosol and cloud properties were made concurrent with cruise JR288, using the BAS Twin Otter aircraft (MASIN) operating out of Svalbard. The campaign is the second of two to take place in the study area as part of the ACCACIA project; the first took place in March 2013 on board the ship RV Lance and the BAS MASIN and FAAM BAe146 aircraft.

Stations were occupied in open water and within the ice edge (mainly small floes). At each station, the following activities typically took place:
1. Shallow CTD cast to sample the upper water column for analysis and use in ship-board experiments
2. Deployment of sea-surface microlayer sampling boat
3. Bongo nets for copepod collection
3. VMP deployment
4. Deep CTD cast to profile the full water column

Additional sampling from the pumped underway seawater supply also took place, and extra deployments of the VMP profiler were made between selected stations. Atmospheric measurements were made continuously, or semi-continuously.

Within ACCACIA, the aims of the research cruise were to make surface based in-situ measurements of marine aerosol composition and properties, and aerosol precursor gases (DMS, VOCs, halocarbons). Trace gases were measured in air and water, and high volume aerosol samples were collected for off-line characterisation of organic composition. Ambient aerosol measurements and bubble tank experiments were conducted to characterise aerosol physical and chemical properties using a suite of instrumentation by the Manchester group. Together with black carbon/soot optical measurements and CCN measurements made as function of particle size and super-saturation, these will be used as input in cloud microphysical models to investigate their influence on aerosol-cloud feedback sensitivity whereas bubble tank results will be used to develop a primary multicomponent sea-spray aerosol flux parameterisation.
