Observing and Understanding the Ocean below Antarctic Sea Ice and Ice Shelves (OASIIS)

OASIIS is a working group of the Partnership for Observation of the Global Oceans (POGO).

SOOS facilitated the development of this working group within POGO. 

The core goal of OASIIS is to develop a detailed implementation plan for an under-ice observing system, including definition of quantitative sampling requirements and identification of leaders (teams) to take implementation of key elements of the observing system forward. For detailed information on what this working group will do, download the POGO proposal here.

Overview

Understanding the interactions between the Southern Ocean, atmosphere and cryosphere is fundamental to our understanding of global climate, biogeochemical cycles, biological productivity and sea-level rise. Despite this global imperative, the ocean beneath the Antarctic sea ice and ice shelves remains one of the least observed physical systems on the planet. This has limited our progress in understanding air-ice-ocean interactions and their sensitivity to climate change. The only way to fill this gap - the largest ‘blind spot’ in the global ocean observing system – is an internationally coordinated, integrated and circumpolar under-ice observing system in the Southern Ocean.


A “truly global” ocean observing system must include observations of the ocean beneath Antarctic sea ice and ice shelves as these are of critical importance to understanding the impacts of climate change on society. For example, the greatest uncertainty in future sea-level rise is the contribution from the Greenland and Antarctic Ice Sheets. We now know that the fate of the Antarctic Ice Sheet is directly coupled to changes in the surrounding ocean. The Southern Ocean takes up vast amounts of anthropogenic heat and carbon dioxide, helping to slow the rate of climate change, but the future of the Southern Ocean sinks are uncertain. Changes in Southern Ocean sea ice, circulation and chemistry (e.g. acidification) will affect Southern Ocean ecosystems and fisheries and alter nutrient transports with impacts on global productivity. There is increasing demand for short-term ocean forecasts and seasonal predictions that depend on assimilation of observations from the high latitude oceans. Effective policy to mitigate and adapt to climate change requires knowledge of how the ocean-ice-atmosphere system will respond to a warming climate. Sustained observations of the Southern Ocean, including the ocean beneath sea-ice and ice shelves are critical to anticipate and respond effectively to these societal challenges.

OASIIS Workshop, Bremerhaven, Germany, 14-17 June 2017

Location:


The OASIIS meeting will be held at the Atlantic Hotel Sail City, Am Strom 1, Bremerhaven, Germany. See the accommodation section below for links to maps and how to get there. The Atlantic Hotel Sail City is located a short distance away from the Alfred-Wegener Institute, who have kindly agreed to be the local hosts for this meeting.

The meeting will be held over three days (14-16th June 2017) with a fourth day for the development of the manuscript (17th June 2017). Days 1 to 3 will feature themed talks and discussion with Day 4 reserved for the drafting of the manuscript.

 

Registration:

Registration for the meeting has now closed.

Icebreaker:

An Icebreaker event will be held on 13 June, 6:30pm at Villa Seebeck.

Dinner:

A dinner for the meeting will be held on 15 June, 7:00pm at Seute Deern. The cost for the dinner is approximately 30-40 Euro (including drinks). Attendees will need to cover this cost themselves. Please indicate at registration whether or not you plan to attend the dinner.

Workshop Objective:

 

The goal of the meeting is to develop a community-led implementation plan for an under-ice observing system, including quantitative design requirements and identification of leaders (teams) to take implementation of key elements of the observing system forward. The workshop also aims to facilitate collaboration and planning for future joint field programs.

 

Articulating a strong case to the community for an under-ice observing system with clear steps as to how this might be realized, and the societal benefits, will enable scientists/national programs to approach funders with a clear rationale and justification for funding field campaigns, observational infrastructure and technology/capability development.

 

Over the past decade, technological advancements in ocean observing mean we now have the capability to observe beneath the Antarctic sea-ice and ice shelves. Rapid development of technology into the future will allow us to expand upon this core capability and enhance under-ice observations even further. The workshop will outline how we can effectively use existing platforms to form the backbone of an under-ice observing system as well as identifying important new technologies/sensors and how to advance them.


Scope:

 

The meeting focus is on the ocean extending from the winter maximum sea-ice edge to the Antarctic coast (or grounding line). Interactions between the ocean beneath sea ice and beneath glacial ice (ice shelves, glacier tongues) are included. The workshop is focused primarily on the physics (sustained observations, regional pilots/process studies and model-data synthesis) however synergies with chemistry and biology (productivity, biogeochemistry, benthic and sea ice ecology) will be highlighted through featured talks.

Climate:


Bremerhaven’s climate is classified as warm and temperate. Average daily temperatures in June are around 14°C/57°F with lows of 9°C/48°F and highs of 19°C/66°F.
