Optimize Data Quality with Proper Bottle Flushing

Collection of representative water samples using Carousel bottles is important for accurately determining biological and chemical gradients. The development of more technologically advanced instrumentation and sampling apparatus causes sampling package size to increase and bottle soak times to decrease, increasing the probability that insufficient bottle flushing will produce biased results. Qualitative evidence from various expeditions suggests that insufficient flushing may be a problem. Researchers from NOAA National Centers for Environmental Information and University of Maryland Center for Environmental Science presented a Poster on this issue at the Ocean Sciences Meeting in February 2016. See more details on the poster.

Robotic Ocean Floats - Key Parameters Expanded

Photo In a recent article in the journal - Nature, Jeff Tollefson highlights how the next generation robotic explorers are helping scientists document effects of global climate change in world's toughest ocean environments.

The oceans currently absorb about a third of human-created CO2 emissions, roughly 22 million tons a day. While ocean acidification is well documented in a few temperate ocean waters, little is known in high latitudes, coastal areas, and the deep sea. Oceanographers are already using data from more than 3,900 floats in the international Argo array for measuring temperature and salinity for depths up to 2000 meters.

The US SOCCOM project is deploying floats with additional sensors for measuring seawater chemistry and biological activity. The Argo program is considering expansion to include floats upgraded to go as deep as 6000 meters that will provide data visibility on 99% of the world's seawater. The global community is also considering expanding Argo to include biogeochemical floats such as those used in SOCCOM.

Today, Sea-Bird manufactures and supplies SBE 41/41CP CTDs for the global Argo program, SBE 61 CTDs for the Deep Argo program, and Navis floats and a range of sensors such as the SBE 41 CTD, SBE 63 oxygen sensor, ECO/MCOMS fluorometer, SUNA nitrate sensor, and Float Deep pH sensor for SOCCOM.

Sea-Bird Scientific at Oceanology International London


Sea-Bird Scientific recently attended 2016 Oceanology International in London. With more than 8000 participants from over 80 countries, OI offered us a single platform to showcase our new products and existing instruments, as well as discuss new opportunities with customers, collaborators, and partners.


Tech TipTech Tip: Deploying the SBE 32 Carousel

Cruise Season Starting? A reminder of how to care for your SBE 32 Carousel Water Sampler
  • After every cast, prevent salt deposits by rinsing the entire Carousel, including the trigger mechanism, inside and outside of each bottle, and frame, with fresh water.
  • If it will be more than a day until the next cast, remove the latch assembly. Soak the latch assembly in a bucket of fresh water and thoroughly rinse the top of the pylon with fresh water, to prevent salt buildup.
  • Periodically, and if experiencing sticky latches, remove the latch asPhotosembly and soak it in a bucket of warm, soapy, fresh water; rinse with fresh water. If still sticking, open all the latches and place the latch assembly in the dishwasher, with dishwasher soap and a no-heat dry cycle.
  • Periodically inspect the bottle tubing for tears and to insure the proper amount of tension.
  • Store the Carousel with bottles closed to preserve the tension in the bottle tubing. If storing on deck, cover at least the latch assembly, and preferably cover the entire Carousel.

CAUTION: Do not oil the trigger mechanism!

For more details, including how to remove and replace the latch assembly, see Application Note 66 on our website.

Prior to joining Satlantic in 1999, Geoff worked with Dalhousie's Department of Oceanography. Geoff began his career with Sea-Bird Scientific as Field Support Scientist and participated in several international multi-disciplinary oceanographic research programs, logging months of sea-time in the Atlantic, Pacific, and Southern oceans. Geoff's role has evolved over the years to include responsibilities in project management, product development, sales and marketing. Nearly 20 years of involvement in scientific research and technology development projects have given Geoff a good understanding of the challenges researchers face in collecting robust and meaningful data in harsh and remote environments.

Geoff is a lifelong resident of Canada's Maritime Provinces, having grown up in Prince Edward Island before moving to Nova Scotia to attend university. In his spare time, he enjoys surfing, snowboarding, and golfing with his three children, travelling internationally with his wife, and riding his motorcycle by himself. Geoff is involved in the local community as coach, event manager, and fundraiser.
