• Assessment of Atmospheric Reanalyses With Independent Observations in the Weddell Sea, the Antarctic 

      Jonassen, Marius Opsanger; Valisuo, Ilona; Vihma, Timo; Uotila, Petteri; Makshtas, Alexander, P.; Launiainen, Jouko (Peer reviewed; Journal article, 2019)
      Surface layer and upper‐air in situ observations from two research vessel cruises and an ice station in the Weddell Sea from 1992 and 1996 are used to validate four current atmospheric reanalysis products: ERA‐Interim, ...
    • Electron Density Depletion Region Observed in the Polar Cap Ionosphere 

      Bjoland, Lindis Merete; Ogawa, Y.; Løvhaug, Unni Pia; Lorentzen, Dag Arne; Hatch, Spencer Mark; Oksavik, Kjellmar (Journal article; Peer reviewed, 2021)
      This paper presents and discusses electron density depletion regions observed with the incoherent scatter EISCAT Svalbard Radar (ESR) located at 75.43°N geomagnetic latitude. The data include several decades of measurements, ...
    • Inconsistent Wind Speed Trends in Current Twentieth Century Reanalyses 

      Wohland, Jan; Omrani, Nour-Eddine; Witthaut, Dirk; Keenlyside, Noel (Peer reviewed; Journal article, 2019)
      Reanalysis data underpin much research in atmospheric and related sciences. While most reanalysis only cover the last couple of decades, National Oceanic and Atmospheric Administration (20CR) and European Centre for ...
    • Long-Term Statistics of Observed Bubble Depth Versus Modeled Wave Dissipation 

      Strand, Kjersti Opstad; Breivik, Øyvind; Pedersen, Geir; Vikebø, Frode Bendiksen; Sundby, Svein; Christensen, Kai Håkon (Journal article; Peer reviewed, 2020)
      Air bubble penetration depths are investigated with a bottom‐mounted echosounder at a seabed observatory in northern Norway. We compare a 1‐year time series of observed bubble depth against modeled and estimated turbulent ...
    • A North-South Contrast of Subsurface Salinity Anomalies in the Northwestern Pacific From 2002 to 2013 

      Yan, Youfang; Svendsen, Lea; Wang, Chunzai; Keenlyside, Noel; Xu, Dazhi (Peer reviewed; Journal article, 2019-03)
      This paper finds a north‐south contrast of subsurface salinity trend during 2002–2013 in the northwestern Pacific. Both Argo float data and long‐term repeat hydrographic measurements along the 137°E section show that ...
    • Snowfall and Water Stable Isotope Variability in East Antarctica Controlled by Warm Synoptic Events 

      Servettaz, Aymeric P. M.; Orsi, Anaïs; Curran, Mark A. J.; Moy, Andrew D.; Landais, Amaelle; Agosta, Cécile; Winton, V. Holly L.; Touzeau, Alexandra; McConnell, Joseph R.; Werner, Martin; Baroni, Mélanie (Journal article; Peer reviewed, 2020)
      Understanding climate proxy records that preserve physical characteristics of past climate is a prerequisite to reconstruct long-term climatic conditions. Water stable isotope ratios (δ18O) constitute a widely used proxy ...
    • Under-Ice Phytoplankton Blooms in the Central Arctic Ocean: Insights From the First Biogeochemical IAOOS Platform Drift in 2017 

      Boles, Elisabeth; Provost, Christine; Garçon, Veronique; Bertosio, Cécilia; Athanase, Marylou; Koenig, Zoé Charlotte; Sennéchael, Nathalie (Journal article; Peer reviewed, 2020)
      In April 2017, the first Ice Atmosphere Arctic Ocean Observing System (IAOOS) platform equipped with biogeochemical sensors was deployed near the North Pole. Over the next 8 months it meandered southward with the ice, ...
