SUMMARY:Oil Slick Thickness Measurement using Thermal Sensors in Arctic En
 vironments
DESCRIPTION:Paper\n\nWesley Lambert (University of New Hampshire, Coastal 
 Response Research Center); Lisa DiPinto (National Oceanic and Atmospheric 
 Administration (NOAA), Office of Response and Restoration); Nancy Kinner (
 University of New Hampshire, Coastal Response Research Center); Oscar Garc
 ia (WaterMapping, LLC); Dana Tulis (United States Coast Gaurd); and Alex B
 alsley (United States Coast Gaurd, Research and Development Center)\n\nThe
  U.S. Coast Guard (USCG) Research and Development Center (RDC), National O
 ceanic and Atmospheric Administration (NOAA) and Coastal Response Research
  Center (CRRC) conducted a series of experiments from May 29th to June 3rd
 , 2022 in Oliktok, AK, as part of continued effort to advance detection of
  oil using uncrewed aerial systems (UAS) during Arctic oil spills. These e
 xperiments were a follow up to studies conducted in April 2021 at the Cold
  Regions Research and Engineering Laboratory (CRREL) in Hanover, NH. The e
 xperiments at CRREL served as initial steps towards operations of UAS plat
 forms for oil spill response. Several questions remained after the CRREL e
 xperiments that required further research in the Arctic regarding UAS and 
 detection operations. Refining and expanding the ability to use UAS platfo
 rms with thermal and multispectral sensors to detect, characterize, and ma
 p surface oil thickness in ice infested water was a key objective of the e
 xperiments. The Oliktok experiments with Alaska North Slope crude and mari
 ne diesel provided a multitude of findings regarding detection of oil thic
 kness in cold waters and relationships that needed to be confirmed with ad
 ditional experiments. For example, during tote experiments, apparent tempe
 ratures measured by the thermal sensor progressively increased as oil thic
 kness increased on the warmer days, but plateaued at thicknesses ≥ 1,000 µ
 m. When light levels and water temperatures were relatively low, the chang
 e in apparent oil temperatures with oil thickness was dampened. Cold tempe
 ratures, and the presence of ice also dampened the relationship. Flight al
 titude affected apparent temperature results indicating that altitude is a
 lso a control variable. From March 13th through the 15th, 2023, additional
  oil and ice experiments were conducted by the USCG Great Lakes Center of 
 Expertise, NOAA, and CRRC at Lake Superior State University in Sault Ste. 
 Marie, MI with similar objectives aimed at refining the relationships rela
 ting oil thickness to apparent temperature observed in Oliktok. These expe
 riments allowed the team to validate the relationships between water tempe
 rature, light levels, and the ability of thermal sensor apparent temperatu
 re data to determine oil thickness of crude oil and diesel slicks in water
 s ranging from 32 to > 45oF. The family of calibration curves developed fo
 r the thermal sensor as a function of water temperature, light levels, and
  altitude for crude oil and diesel will be presented, along with the assoc
 iated caveats, for oil slick thickness measurement in cold climates.\n\nTa
