Arctic Polar Research - A Global Responsibility

Due to climate change and geopolitical trends, the Polar Regions (particularly the Arctic) are increasingly becoming the focus of scientific, political, and economic interests. Much of the global climate is driven by forces that originate in the Arctic. The Arctic sea ice is receding faster than climate models have predicted, and the movement of freshwater into and around the Arctic plays an important role in shaping both regional and global climate.

In response to a joint request from the World Climate Research Program's Climate and Cryosphere Project, the International Arctic Science Committee, and the Arctic Council's Arctic Monitoring and Assessment Program, an updated scientific assessment has been conducted on the Arctic Freshwater System, entitled the Arctic Freshwater Synthesis (AFS). The major reason behind the joint request was an increasing concern that changes to the Arctic Freshwater System have produced, and could produce even greater, changes to bio-geophysical and socioeconomic systems of special importance to northern residents as well as extra-Arctic climatic effects that will have global consequences. We are all responsible for the amplified effects of climate change in Polar Regions. For our part, we are ensuring our instruments and sensor systems are fully tested in cold water conditions and designed to remain stable in the long-term remote applications that are common in polar region research. For tips on using Sea-Bird Scientific instruments in icy conditions, please see the Tech Tip section below.

Notice of Email Domain Change

In 2011, Sea-Bird Scientific was created to combine the capabilities of Sea-Bird Electronics, WET Labs, and Satlantic and to provide best-of-class sensors and systems for oceanographic research and environmental water quality monitoring.

As part of our evolution as a single organization, we are migrating all of our email accounts to a single domain starting November 19, 2016. The old WET Labs ( and Satlantic ( email addresses will still work (forwarded to the new domain), but you will receive replies from the domain. We recommend that you update your address books next week after the change takes place.

Tech Tip: Deploying Sea-Bird CTD in Ice

Large numbers of Sea-Bird conductivity instruments have been used in Arctic and Antarctic programs. Special accommodation to keep temperature, conductivity, oxygen, and optical sensors at or above 0 °C is advised. Often, the CTD is brought inside protective doors between casts to achieve this.

Conductivity Cell
When freezing is possible, we recommend that the conductivity sensor be stored dry. Remove larger droplets of water by blowing through the cell. Do not use compressed air, which typically contains oil vapor. Attach a length of Tygon tubing to each end of the conductivity cell to close the cell ends. See Application Note 2D: Instructions for Care and Cleaning of Conductivity Cells for details.

Temperature Sensor
In general, neither the accuracy of the temperature measurement nor the survival of the temperature sensor will be affected by ice.

Oxygen Sensor
For the SBE 43 and SBE 63 Dissolved Oxygen sensors, avoid prolonged exposure to freezing temperature, including during shipment. Do not store with water (fresh or seawater), Triton solution, alcohol, or glycol in the plenum. The best precaution is to keep the sensor indoors or in some shelter out of the cold weather.
