Project details

Title: Southern Ocean continuous plankton recorder
Id: 2495
Investigator(s): AAD
Australian Antarctic Division [details]

Description: The SCAR Southern Ocean Continuous Plankton Recorder (SO-CPR) Survey was established in 1991 by the Australian Antarctic Division to map the spatial-temporal patterns of plankton biodiversity and use the sensitivity of plankton to environmental change as early warning indicators of the health of the Southern Ocean. It also contributes to or can serve as a reference for other observational/monitoring programmes such as the Southern Ocean Observing System (SOOS), Southern Ocean Sentinel (SOS), CCAMLR Ecosystem Monitoring Program (C-EMP), and the Integrating Climate and Ecosystem Dynamics (ICED) program.
Years: 2019

Survey InvestigatorDescription

Michael Double (AAD) RV Investigator research voyage in2019_v01, titled "The availability of Antarctic krill to large predators and their role in biogeochemical recycling in the Southern Ocean." The voyage is also known as "ENRICH (Euphausiids and Nutrient Recycling in Cetacean Hotspots)". We will operate south of 60°S, northward of the ice edge, and between 140°E and 175°W. The specific study area/s within these boundaries will be determined by the locations of vocalising Antarctic blue whales, krill and sea-ice. The survey design is therefore adaptive in that sites will be chosen in real-time on the voyage according to available information. At the commencement of the voyage we will head straight to the closest group of vocalising Antarctic blue whales (ABWs) within our operational area. Vocalising ABWs are able to be detected through sonobuoys (see below) hundreds of kilometres away. When whales are found we will undertake a series of activities at that site. We will then commence a series of line transects in the same region and remain within the same area for the rest of the voyage. The study is therefore on a mesoscale and we do not aim to cover our entire operational area. The activities required to achieve our voyage objectives are: • Passive Acoustics • Whale observing, video-tracking and biopsy • Active Acoustics • Krill trawls • Unmanned Aerial Systems (UASs) • Biogeochemistry
