DY151 SEANA/M-Phase Research Cruise
DY151 Aim and Objectives
The overall aim is to reduce the uncertainties in modelling the response of sources and processes of aerosol, cloud condensation nuclei, and ice nuclei to anthropogenic and natural emission changes so that we can better simulate clouds and predict future climate in the Arctic. The cruise is atmospheric focused. The main objectives include:
- To understand the sources and processes of aerosol particles (such as black carbon and dust), cloud condensation nuclei and ice nuclei (coarse particles are key)
- To elucidate the formation and growth mechanism of new particles
- To update a global aerosol model based on mechanistic understanding on particle source and processes from the observations.
- To evaluate the new model against pan-Arctic observations
- To predict the potential impact of future shipping emissions along the Northwest Passage (likely to be completely open in the summer by 2050) and changing climate on aerosol, CCN, IN and clouds
- To understand the impact of high latitude dust deposition on ocean nutrient pool and on phytoplankton growth
RRS Discovery
The RRS Discovery is a multidisciplinary ship, operated by National Oceanographic Center. RRS Discovery was designed by A.S. Skipsteknisk and was delivered to the National Oceanography Centre on the 8 July 2013.
With the ability to travel to remote and extreme oceanic environments, RRS Discovery is highly sophisticated and has the ability to operate in high sea states (up to sea-state 6). The ship comes with sub-bottom profiling and multi-beam equipment for mapping the seabed, while her dynamic positioning capability means that Remotely Operated Vehicles can be used. Her wide range of cranes and over-side gantries, with associated winches and wires, will allow many different types of equipment to be deployed from the ship. These facilities and the many more listed below help support the marine science community as it undertakes research of national and global importance.
Research Area
The cruise will go to the Labrador Sea. We will start at Iceland (Reykjavik) from 19 May 2022 (mobilisation from 16-18 May) and back to Southampton (UK) on 27 June. The areas we are interested in are shown in the picture to the right [click to enlarge] – we are interested in both dust and terrestrial aerosols, as well as gas / aerosol emissions from the melting sea ice. We have a range of gas, aerosol, CCN, IN observations (see attached).
