SAMI-CO2 Instruments Help Our Understanding of the Role of the Arctic Ocean in Climate Variability

 

In September of 2018, two ice-tethered profilers (ITP) with SAMI-CO2 instruments were deployed beneath Arctic sea ice. The ITPs include a surface buoy with satellite transmitter and CTD profiler that measures physical and biogeochemical properties from the surface to 800 m depth. The SAMIs are deployed directly under the ice at ~6 m. The ITPs are analogous to the Argo float program that deploys profiling floats in the oceans (Figure 1). Cory Beatty from Mike DeGrandpre’s lab at the University of Montana was part of the 2018 expedition, deploying SAMI-CO2 instruments on two of the ITPs (ITP 107 and 110). Sunburst worked with Beatty to configure the SAMIs to transmit data in real time via an inductive modem. pCO2 measured at ITP 107 is shown in Figure 2. The complete data sets can be viewed and downloaded www.whoi.edu/itp.  Click below for pictures and a look at some data.

Sunburst Sensors LLC makes generous donation to Climate Smart Missoula

MISSOULA, MT (October 9, 2015) – Sunburst Sensors LLC announced they are donating $10,000 from their recent Wendy Schmidt Ocean Health XPRIZE to the newly launched community initiative, Climate Smart Missoula. Sunburst Sensors is a Missoula-based manufacturing company which makes devices to measure changes in ocean chemistry and is co-owned by James Beck and Michael DeGrandpre.

“Climate Smart Missoula is a grass roots group working locally to reduce our climate impacts and we are excited to help support their efforts”, say Beck and DeGrandpre.   “We’re not getting sufficient action from the top-down on this issue, so it’s up to cities and states to act on their own.  Though we are a manufacturing company with customers around the world, we try to use local suppliers and want to support our community.  Winning the recent XPRIZE awards gives us an opportunity to do something extra.”

“We are thrilled and honored to be the recipient of such a generous donation,” said Amy Cilimburg, Director of Climate Smart Missoula. “This donation is crucial seed money as we work to fulfill our mission: to be the hub that fosters partnerships and actions to address climate change in our community. We hope this encourages others in our community to consider being part of climate solutions by sharing their time, innovative ideas, or financial contributions with us.  It’s an exciting time to catalyze change right here in Missoula, Montana.”

Sunburst Sensors Advances to Phase 3 of $2 Million Wendy Schmidt Ocean Health XPRIZE

 

Missoula, Mont. (February 20, 2015) - Sunburst Sensors, LLC, a Missoula, Montana based company, has advanced to the third phase of the $2 million Wendy Schmidt Ocean Health XPRIZE, a global competition that challenges individuals and teams to build innovative pH sensor technology that will accurately measure and advance the understanding of ocean acidification. The 14 remaining teams are competing for two prize purses: the $1M accuracy purse, based on performance, and the $1M affordability purse based on cost and usability.

Earlier this month, teams submitted their sensor for a month-long performance test in a coastal environment at the Seattle Aquarium, where each device will make hourly measurements over the course of a 30-day period and have them compared to reference laboratory pH readings. Sunburst Sensors has entered two separate instruments in the competition both based on their existing product, the SAMI-pH. To compete for the affordability purse, Sunburst Sensors developed the iSAMI-pH, with the ‘i’ standing for ‘inexpensive.’

“Because the affordability purse does not require the same level of accuracy or measurements in deep water, we could greatly simplify our design using less expensive parts,” said James Beck, President of Sunburst Sensors. “It’s not pretty but it works well.”

The company has also entered the tSAMI-pH for the accuracy purse, which has a 3000 meter depth requirement. This sensor was designed for the next phase of the competition, which includes deep-sea trials in the Pacific Ocean off the coast of Hawaii that will put devices through real-world depth and pressure scenarios, slated to take place in May 2015.

Sunburst Sensors Advances to Finals of $2 Million Wendy Schmidt Ocean Health XPRIZE

Missoula, Mont. (April 29, 2015) – Sunburst Sensors, LLC, a Missoula, Montana based company, has advanced to the final phase of the $2 million Wendy Schmidt Ocean Health XPRIZE, a global competition to create innovative pH sensor technology that will accurately measure and advance the understanding of ocean acidification.

Beginning on May 14 in Honolulu, teams will board the R/V Kilo Moana, a research vessel owned by the U.S. Navy and operated through UNOLSby the University of Hawaii Marine Center, and embark on a week-long deep sea trial to assess ocean pH values throughout the water column at Station ALOHA, a 110 square mile region in the Pacific Ocean, located approximately 100 miles off the northern shore of Oahu. During this six-day period, sensors will be put through rigorous performance tests focused on stability and precision, while battling real-world pressure scenarios at depths of up to 3,000 meters.

Sunburst Sensors’ ‘tSAMI-pH’ device was designed to handle extreme conditions by using a titanium pressure housing that should allow it to survive the 3000 meters deployment depth. The instrument will collect pH data as it descends and is raised back to the surface.

“We are honored to find ourselves in the finals of the Wendy Schmidt Ocean Health XPRIZE,” said James Beck, Sunburst Sensors CEO. “This contest has brought together some very talented teams and smart people from all around the world. To make it this far is a testament to the hard work we’ve put into our products. It has spurred us to pursue some ideas we might not have tried otherwise. Whatever the outcome, this has been a valuable learning experience for everyone at our company.”
