SONA Objectives

Strategic objectives

1. Lead, coordinate and support the Antarctic scientific community in generating an open access database of acoustic observations of the mid-trophic level.

  • To maintain and develop coordination and communication between the different science and national programmes within SONA.
  • To determine and adopt calibration and acoustic data collection and processing protocols to ensure high quality common data collection.
  • To enable the implementation of the South Atlantic Science, South Atlantic Opportunistic and Southern Ocean Baseline Acoustic databases.
  • To develop the SONA data discovery and data access website and determine open-access procedures for the databases.
  • To actively expand the network of partners and supporters in terms of geographic representation and expertise.

2. To implement a self-sustaining long-term acoustic observing strategy framed within the international observing and modelling communities.

  • To support and organise an international workshop that will advance our knowledge of the status of the ecosystem of the South Atlantic sector of the Antarctic, focussing on the mid-trophic level.
  • To create an atlas of mid-trophic level distribution in the Southern Ocean with associated qualification of uncertainties.
  • To support and organise an international workshop that will advance our knowledge of the status of the Southern Ocean ecosystem, focussing on the mid-trophic level
  • To coordinate activities leading to high impact outputs that include publication of the SOBA atlas, and peer-reviewed literature outputs from the workshops.
  • To liaise with international programmes such as SOOS and AntaBIF for the long-term stewardship and funding of the databases.
  • To interact with the ICED (Integrating Climate and Ecosystems Dynamics) community to integrate mid-trophic level measurements into ecosystem models in order to address issues pertaining to Southern Ocean food-web structure and scenarios of change that will influence the IPCC process.

Scientific objectives

  • Determine a baseline and establish methods to determine long-term trends in the distribution of mid-trophic level organisms in the South Atlantic part of the Southern Ocean.
  • Determine a baseline and establish methods to determine long-term trends in the circumpolar distribution of mid-trophic level organisms in the Southern Ocean.
  • Provide and advise on a mid-trophic level component to the Southern Ocean ecosystem to the scientific community (ICED and CCAMLR) for integration into models concerning biogeochemical processes and ecosystem based fisheries management.
