 Sunburst Sensors Instruments Used to Study Arctic Carbon Cycle

Researchers have used the SuperCO2, SAMI-CO2 and SAMI-pH along with other instruments to learn more about the changing carbon cycle in the arctic.

From the linked article:

Sea surface pCO₂ variability in the Arctic Ocean is intertwined with biological production, ice formation, and melting (where CO₂ is concentrated or diluted, respectively), heating and other processes, all of which are no longer in steady state. Sparse long-term data have limited our ability to assess variability of sea surface pCO₂ that is related to these changes.

(The authors) have been measuring pCO₂ in the Canada Basin of the Arctic Ocean since 2012 to help address this shortcoming. Cruises have taken place on the Canadian icebreaker, the CCGS Louis S. St-Laurent as part of the Beaufort Gyre Observing System and Joint Ocean Ice Study (BGOS/JOIS) programs through Woods Hole Oceanographic Institution (Woods Hole, Massachusetts) and the Institute of Ocean Sciences (Sidney, British Columbia), respectively. These cruises, conducted since 2002 with support from NSF, have focused on the hydrography and biogeochemistry of the western Arctic Ocean.

The Ocean Observatories Initiative (OOI) uses both SAMI-CO₂ and SAMI-pH instruments at many of its observatories to help monitor the marine carbonate system. OOI recently published an article: Altered Carbon: Improvement to CO₂ Measurements Enhance OOI Data Quality  (Link will open new tab/window)

 Sunburst Demonstrates SAMI-CO₂ at ICOS OTC 2019

Sunburst Sensors was invited to participate in the 2nd Integrated Carbon Observation System Ocean Thematic Centre (ICOS OTC) sensor workshop at GEOMAR in Kiel, Germany in November 2019. The purpose of the 3-day workshop was to train ICOS members in best practices for CO₂ measurements, as well as instrument maintenance and data handling. Reggie Spaulding presented SAMI-CO₂ best practices, maintenance, and quality control. Approximately 30 members from across Europe attended.

ICOS will sponsor a pCO₂ measurement intercomparison exercise in 2021 at the Flanders Marine Institute in Belgium. The exercise will focus on underway instruments. We plan to test our SuperCO₂ and our AFT-CO₂ instruments.

Sunburst Participates in Commuter Challenge for 10th year

Sunburst employees have been participating in Missoula in Motion's annual Commuter Challenge for 10 years.  Missoula in Motion encourages sustainable transportation, including biking, walking, busing, carpooling, and telecommuting.  Over 100 local businesses participate in the Commuter Challenge each year, with free breakfasts and coffee for participants along bike routes, daily prize drawings, and awards given to companies with the highest percentage of participants.  in 2010 and 2011 Sunburst won the challenge in the micro-business category, with 100% participation.  This year Sunburst is again on the All-Star list, with 9 of 10 employees participating.


Sunburst has a casual atmosphere where employees are encouraged to commute sustainably.  On any summer day you will typically see several bikes in the offices and open spaces at Sunburst.    Brandon Wasser is our sustainable commute star.  He rides his bike to work every day, regardless of winter snow, spring rain, or summer heat, and he volunteers at Free Cycles, helping locals fix up their bikes or build bikes from up-cycled parts for free!
