Cruise Inventory Information
| Long name | Lance (58LA) cruise ACCACIA |
|---|---|
| Short name | ACCACIA |
| 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 the RV Lance research cruise, using the BAS MASIN and FAAM BAe146 aircraft, and a second research cruise on board the RRS James Clark Ross will take place in July-August 2013.
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). These measurements were supported by standard oceanographic measurements such as salinity, chlorophyll-a and nutrient concentrations. Bubble tank experiments were conducted, the results of which will be used to develop a primary multicomponent seaspray aerosol flux parameterisation. The timing of the cruise was intended to capture the late winter/early spring period of sea-ice melt and the associated phytoplankton bloom has just begun. Stations were occupied alternately in open water and within the ice edge (mainly brash ice). Atmospheric measurements were made continuously, or semi-continuously, and a daily CTD cast was used to collect water samples. Some additional sampling of the pumper underway seawater supply also took place. |
