 | The Marginal Ice Zone (MIZ) intensive field program will employ an array of cutting-edge autonomous platforms to characterize the processes that govern Beaufort Sea MIZ evolution from initial breakup and MIZ formation though the course of the summertime sea ice retreat. Instruments will be deployed on and under the ice prior to initial formation of the MIZ along the Alaska coast, and will continue sampling from open water, across the ... |

| The long-term goals of this project are to create a new capability for under-ice acoustic navigation and communication, specifically in support of the ONR Marginal Ice Zone (MIZ) Departmental Research Initiative (DRI). The MIZ DRI field program will occur in 2014, with trials starting in 2013. The MIZ DRI will include a large array of sensors deployed on the surface of the ice, as well as Sea Gliders and drifters ... |

|
| Long term goals are to observe and model processes controlling ice retreat in the marginal ice zone (MIZ), the narrow strip between open ocean and the ice pack where the seasonal retreat of the main ice pack takes place. It is a highly variable sea ice environment, usually comprised of many individual floes of variable shape and size and made of mixed ice types, from young forming ice to fragmented ... |

Jim Thomson; WASHINGTON UNIV SEATTLE APPLIED PHYSICS LAB
|
| The long-term goal is to improve prediction of the arctic Marginal Ice Zone (MIZ) by improving basic understanding of the interaction between waves, sea ice, and open water (i.e., fetch). The primary objective is to improve wave source/sink parameterizations by directly measuring the growth and dissipation of waves in the MIZ. The secondary objective is to develop a surface wave climatology of the arctic ocean and the relation to the ... |

|
| Our research seeks to build understanding of upper-ocean processes and ice-ocean interactions in the polar oceans (Arctic and Southern Ocean). Particular areas of focus include ice-ocean exchanges of momentum, heat and salt, mixed layer variability including layer deepening, vertical entrainment and restratification processes, and internal wave dynamics and associated turbulent mixing. With better understanding of the physical processes, improved model parameterizations and in turn, model predictions will result. |

|
| ONR grant N00014-98-1-0037, "Arctic Mixed Layer Dynamics," is the last in a series of Arctic Mixed Layer Grants extending over more than 20 years. Throughout that time our approach has been to bring new tools to bear on fundamental questions about mixing in the upper ocean, particularly the mixed layer and underice planetary boundary layer. Over the years we have sought to understand the heat and mass balance of the ... |

|
| This report describes numerical simulation of two types of idealized drifters: pure Lagrangian drifters and the isobaric drifters. A large eddy (LES) model was used to predict the fully turbulent non-hydrostatic evolution of the oceanic flow fields that are typical of the Labrador Sea. The LES simulation indicates that either free or forced convection may dominate, depending upon the magnitudes of the wind stress and the net surface heat fluxed ... |

|
| Phytoplankton associated with the ice edge in the Barents Sea during the spring and summer is one of the most productive areas in the world oceans. These blooms move northward as the ice recedes, creating a belt of production at the marginal ice zone. Given the complexity of the physical environment and the extremes in solar radiation, the blooms are highly dependent on the variability associated with the environment. In ... |

|
| The long-term goals are to understand how the marginal ice edge zone (MIZ) interacts with the open ocean in an oceanographic/meteorological/ biological sense. This includes understanding the processes and dynamics for the generation, dissipation and role of mesoscale eddies and chimneys in the MIZ (and in the open ocean after the ice has retreated or melted) in the Greenland Sea/Fram Strait. A further goal is to understand how these physical ... |

|
| Many measurements of volume reverberation have been conducted in the open oceans of the world. In May 1988, the Naval Research Laboratory at Stennis Space Center (NRL-SSC) had the opportunity to investigate volume reverberation in a unique region: the marginal ice zone (MIZ) of the Fram Strait between Spitsbergen and Greenland. Measurements were made from a drifting ice camp at three locations over a four day period. Volume scattering strength ... |

Titled 'Eastern Arctic Ice, Ocean and Atmosphere Data, Volume 1, CEAREX-l' , the disc contains meteorology, hydrography (CTDs), biophysical sampling, bathymetry, sea ice acceleration, sea ice stress, sea ice deformation, and ambient noise/ acoustics samples. The disc is the ... |

|
| Changes in areal extent and concentration of sea ice around Antarctica may serve as sensitive indicators of global warming. A comparison study was conducted between the outputs of the three main algorithms currently in use (NASA Team, Comisco, and NORSEX) and a sea-ice model (Fine Resolution Antarctic Model). Data from the DMSP Special Sensor Microwave/Imager (SSM/I) were used as input algorithms for the time frame July, 1987 to June, 1990. ... |

|
| The combination of numerical models and observational data can provide a unique tool for studying the complex interactions of the atmosphere, the ice, and the ocean. The formulation of numerical ice and coupled ice-ocean- atmosphere models is based on our knowledge of dynamic and thermodynamic principles and how they relate to observed ice conditions. Field experiments such as the Arctic Ice Dynamics Experiment (AIDJEX) Pritchard, 1980 and the Marginal Ice ... |

|
| Ambient noise measurements made northeast of Svalbard from two omni- directional hydrophones, deployed at 60 and 90 m beneath the ice, were acquired as the research vessel Polarbjoern drifted southward from 11 October to 18 November 1988. The ambient noise data as well as the accompanying meteorological and ice motion data were collected as part of the Coordinated Eastern Arctic Experiment, CEAREX. The ambient noise measurements were composed of one ... |
