    • A low-cost coastal buoy for ice and metocean measurements 

      Petrich, Christian; O'Sadnick, Megan Eileen; Kleven, Øystein; Sæther, Irina Vasiljeva (Peer reviewed; Journal article, 2019)
      Regionally, an ice cover in fjords of mainland Norway may form and break up repeatedly during winter. Due to relatively high water temperatures, the freeze-up process is expected to be related to freshwater-induced ...

    • Effect of Oil Pollution and Ice Formation on Microbial Community of Seawater from Ofotfjorden, Norway 

      Dang, Nga Phuong; Willassen, Nils Peder; O'Sadnick, Megan Eileen; Petrich, Christian (Chapter, 2018)
      Oil spill in ice-covered waters can become entrapped in sea ice and may be subjected to biodegradation by sea ice microorganisms. The extent of the hydrocarbon biodegradation, and microorganisms involved in such process ...

    • Examination of Sea Ice Cover in Norwegian Fjords 

      O'Sadnick, Megan Eileen; Petrich, Christian; Brekke, C; Skarðhamar, J. (Lecture, 2017)
      Presented are two steps being taken to examine sea ice coverage in Norwegian fjords as part of a larger study to improve our understanding of ice formation and breakup processes in these regions and implications for oil ...

    • Ice extent in sub-arctic fjords and coastal areas from 2001 to 2019 analyzed from MODIS imagery 

      O'Sadnick, Megan Eileen; Petrich, Chris; Brekke, Camilla; Skardhamar, Jofrid (Peer reviewed; Journal article, 2020)
      Results examining variations in the ice extent along the Norwegian coastline based on the analysis of Moderate Resolution Imaging Spectroradiometer (MODIS) images from 2001 to 2019,February through May, are presented. A ...

    • Measurements to Estimate the Downward Heat Flux from a Burning Oil Pool 

      Petrich, Christian; O'Sadnick, Megan Eileen; Dang, Nga Phuong; Stakkeland, Linda Marie; Kristiansen, Steffen (Chapter, 2018)
      Oil spills in ice-covered waters pose unique challenges to remediation activities. In-situ burning is a potential remediation technique that has shown promising efficiency in earlier trials. An element of in-situ burning ...

    • MOSIDEO/CIRFA Experiments on Behavior and Detection of Oil in Ice 

      Petrich, Christian; O'Sadnick, Megan Eileen (Lecture, 2017)
      - Preparedness and response to oil in sea ice-covered waters - When does oil melt out of the ice - When can oil be detected with remote sensing techniques?

    • Mosideo/cirfa tank experiments on behavior and detection of oil in ice 

      Petrich, Christian; O'Sadnick, Megan Eileen; Brekke, Camilla; Myrnes, Marianne; Maus, Sønke; Salomon, Martina Lan; Woelk, Sofie; Grydeland, Tom; Jenssen, Rolf-Ole Rydeng; Eicken, Hajo; Oggier, Marc; Ferro-Famil, Laurent; Harkati, Lekhmissi; Rebane, Ott; Reimer, Nils (Peer reviewed; Journal article, 2019)
      In the Arctic, presence of sea ice presents a challenge to safe and sustainable operations. To optimize planning and minimize impact of inadvertent oil spills, oil-in-ice experiments were performed at the HSVA Arctic ...

    • Observations of Ice Conditions and Properties in Norwegian Fjords during the Winter of 2018 and Implications for Oil Spill Response 

      O'Sadnick, Megan Eileen; Petrich, Christian; Kleven, Øystein; Brekke, Camilla; Skarðhamar, J.; Dang, Nga Phuong (Chapter, 2018)
      As the arctic opens to more development and increasing ship traffic, coastlines are at greater risk of oil pollution resulting from these operations. Fjords are one feature common throughout the arctic, with many dotting ...

    • Recent ice conditions in North-Norwegian Porsangerfjorden 

      Petrich, Christian; O'Sadnick, Megan Eileen; Dale, Line (Peer reviewed; Journal article, 2017)
      Ice is a common occurrence in mainland Norwegian fjords in the vicinity of river mouths in winter. Fjord ice provides a wide array of services to society, including (1) acting as a coastal buffer (e.g. from pollution) and ...

    • The Entrainment and Migration of Crude Oil in Sea Ice, the Use of Vegetable Oil as a Substitute, and Other Lessons from Laboratory Experiments 

      O'Sadnick, Megan Eileen; Petrich, Christian; Dang, Nga Phuong (Peer reviewed; Journal article, 2017)
      Understanding the interaction between oil and sea ice is essential in the development of oil spill detection and response technology in the Arctic. Laboratory experiments were performed to examine oil migration in sea ice ...
