Warmer Ocean Estimates: Improved Understanding of the Past

According to a recent finding published in the journal Science Advances, the oceans may be storing 13% more heat than previously estimated. This study, co-authored by scientists at the National Center for Atmospheric Research (NCAR), is based on a new analysis of how ocean temperatures have changed since 1960.
Historically, the studies were limited to areas where ships traveled, but in more recent decades, measurements of ocean heat at remote locations have been possible with the advances in observational techniques - Robotic Ocean Floats. The global Argo program is an array of 3800 free-drifting profiling floats that measure temperature along with other parameters of the upper 2000 m of the ocean. The data collected from Argo floats was used to validate a new estimate of ocean heat content. This study is an example of how advances in technology have enabled an improved understanding of past changes in the ocean and help us understand how future changes might unfold.

Advances in Bio-Optical Sensing on Floats

Autonomous Argo floats have proven to be reliable and economical vehicles for collecting data from remote locations on a world-wide scale. As float technology has proven itself, the range of biogeochemical sensors installed on floats has rapidly expanded. Floats have also increased in mission flexibility, with the ability to perform complex mission plan sequences. Floats can be reprogrammed after release with new mission sequences to, for example, increase the time the float spends in an eddy structure.
Sea-Bird Scientific manufactures its own Navis Float and also contributes widely to the global programs such as Argo and SOCCOM. Sea-Bird manufactures and supplies SBE 41/41CP CTDs for the global Argo program, SBE 61 CTDs for the Deep Argo program, as well as a range of sensors such as the SBE 63 oxygen sensor, ECO/MCOMS fluorescence and backscattering sensor, SUNA nitrate sensor, and Float Deep pH sensor for SOCCOM.
Sea-Bird University Goes Down Under

Last month our scientists visited customers in Australia to provide training on Sea-Bird instruments. Training consisted of comprehensive operator training on major Sea-Bird products and software, data processing and repair.
Sea-Bird Scientific offers regularly scheduled four-day training classes approximately two times per year at an off-site location near our office/factory in Bellevue, Washington (12 miles from downtown Seattle). Through our comprehensive training modules, we teach our customers how to get the most from their instruments. Training consists of operator training on major Sea-Bird products and software, and is hands-on by nature. The curriculum covers profiling instruments, thermosalinographs, and moored instruments, and includes theory and operation, data processing, and maintenance and repair.
See also our training videos on YouTube that cover the first five training modules (0 to 4).
We encourage you to take advantage of our expertise and participate in our training classes. Our next 4-Day training is scheduled for October 16 - 19, 2017. Visit Sea-Bird University for more details, or contact Payal Parikh (firstname.lastname@example.org) to enroll for this class.
Tech Tip: Shipping and Deploying Profiling Floats

Most Argo program floats (Sea-Bird Navis floats as well as most Argo floats from other manufacturers) include an SBE 41/41CP CTD. We have written an Application Note that provides handling and cleaning details, and information on replacing anti-foulant devices. This application note presents recommendations for best practices when preparing profiling floats for deployment and shipping. The Application Note is divided into three sections:
- General guidelines
- Instructions for Care and Cleaning of Conductivity Cells
- Installing or Replacing of Anti-Foulant Device in SBE 41/41CP CTD

2017 Service and Support Survey is Out!
Sea-Bird Scientific is driven by feedback from our customers. We count on customers to tell us about their experiences, so we can provide them with the best data and user experience possible. Last year’s repsonse rate was high and we hope to have feedback from even more of you this year.
The survey should take you about 6-8 minutes to complete and is in two parts, starting with Service and followed by Support. Please take a moment and tell us what you like and don’t like. We look forward to your honest answers to help us serve you better.
Meet Our People: Steve Smith, Sales Application Engineer
Steve has a BS in Mechanical Engineering from Rutgers University. Steve joined Sea-Bird Scientific as an Applications Engineer last month. His role is to help customers determine the best equipment to purchase, based on the application.
Before Sea-Bird, Steve worked at Boeing, and had been involved with sensors and systems for monitoring and control of processes. Steve has vast experience with application of product applications, product marketing, sales, as well as training for end-users, representatives, OEM customers and distributors. His last role involved assisting customers with strain gages for testing and sensor development.
Steve is passionate about building and repairing things, which leads to collecting a wide array of tools (much to the chagrin of his wife). Currently, he is working on a backyard fountain with hammered copper features. Steve enjoys cooking, hiking, photography, music and traveling. Steve also volunteers for a Christmas tree auction fundraising event to support a local non-profit organization.
