A Note on the Ocean Surface Roughness Spectrum
(American Meteorological Society, 2011)In a recent study, the dimensionless surface roughness spectrum has been empirically parameterized as a power-law function of the dimensionless wind speed expressed as the ratio of wind friction velocity and phase speed ... -
Optimal Linear Fitting for Objective Determination of Ocean Mixed Layer Depth from Glider Profiles
(American Meteorological Society, 2010)A new optimal linear fitting method has been developed to determine mixed layer depth from profile data. This methodology includes three steps: 1) fitting the profile data from the first point near the surface to a depth ... -
Quality Assessment of a 1985–2007 Mediterranean Sea Reanalysis
(American Meteorological Society, 2010)simulation and two reanalyses from 1985 to 2007 have been produced for the Mediterranean Sea using different assimilation schemes: a reduced-order optimal interpolation [System for Ocean Forecast and Analysis (SOFA)] and ... -

Study of the Far Wake of a Large Ship
(American Meteorological Society, 2011)large dataset of high-resolution photographic images of far wakes of a volunteer observing ship (Royal Caribbean?s Explorer of the Seas) has been acquired under various meteorological conditions and ship operation modes. ... -
Estimating the Four-Dimensional Structure of the Southern Ocean Using Satellite Altimetry
(American Meteorological Society, 2010)gravest empirical mode (GEM) projection of temperature and salinity fields over the circumpolar Southern Ocean is presented and is used in combination with satellite altimetry to produce gridded, full-depth, time-evolving ... -
Delayed-Mode Calibration of Hydrographic Data Obtained from Animal-Borne Satellite Relay Data Loggers
(American Meteorological Society, 2011)delayed-mode calibration procedure is presented to improve the quality of hydrographic data from CTD?Satellite Relay Data Loggers (CTD?SRDL) deployed on elephant seals. This procedure is applied on a dataset obtained with ... -
Observations of Large-Amplitude Nonlinear Internal Waves from a Drifting Array: Instruments and Methods
(American Meteorological Society, 2010)This paper presents a novel methodology applied to the observation of large-amplitude nonlinear internal waves in the upper ocean from an array of drifting instruments. The characteristics of the instrument used?an Autonomous ... -
Ice-Tethered Profiler Measurements of Dissolved Oxygen under Permanent Ice Cover in the Arctic Ocean
(American Meteorological Society, 2010)Four ice-tethered profilers (ITPs), deployed between 2006 and 2009, have provided year-round dissolved oxygen (DO) measurements from the surface mixed layer to 760-m depth under the permanent sea ice cover in the Arctic ... -
A Novel Integration of an Ultraviolet Nitrate Sensor On Board a Towed Vehicle for Mapping Open-Ocean Submesoscale Nitrate Variability
(American Meteorological Society, 2010)Initial results from a deployment of the SUV-6 ultraviolet spectrophotometer, integrated with the SeaSoar towed vehicle, are presented. The innovative, combined system measures nitrate concentration at high spatial resolution ... -
Quality Controlling Surf Zone Acoustic Doppler Velocimeter Observations to Estimate the Turbulent Dissipation Rate
(American Meteorological Society, 2010)High-quality measurements of the turbulent dissipation rate ? are required to diagnose field surf-zone turbulence budgets. Quality control (QC) methods are presented for estimating surf zone ? with acoustic Doppler velocimeter ... -
Depth Biases in XBT Data Diagnosed Using Bathymetry Data
(American Meteorological Society, 2010)Expendable bathythermograph (XBT) profiles are an important component of the historical record of subsurface ocean temperature. To correct for time-varying biases in these data, adjustments to XBT depths and/or temperatures ... -
Investigation of XBT and XCTD Biases in the Arabian Sea and the Bay of Bengal with Implications for Climate Studies
(American Meteorological Society, 2010)Long time series of XBT data in the Bay of Bengal and the Arabian Sea are valuable datasets for exploring and understanding climate variability. However, such studies of interannual and longer-scale variability of temperature ... -

Wave Heights during Hurricane Katrina: An Evaluation of PPP and PPK Measurements of the Vertical Displacement of the GPS Antenna
(American Meteorological Society, 2010)In August 2005 the eye of Hurricane Katrina passed 49 n mi to the west of a 3-m discus buoy operated by the Central Gulf of Mexico Ocean Observing System (CenGOOS). Buoy motions were measured with a strapped-down 6 degrees ... -
A New Method to Estimate the Systematical Biases of Expendable Bathythermograph
(American Meteorological Society, 2010)A new technique to estimate three major biases of XBT probes (improper fall rate, start-up transient, and pure temperature error) has been developed. Different from the well-known and standard ?temperature error free? ... -
A Spar Buoy for High-Frequency Wave Measurements and Detection of Wave Breaking in the Open Ocean
