The biogeochemistry of continental shelf systems plays an important role in the global elemental cycling nitrogen and carbon, but remains poorly quantified. We have developed a high‐resolution physical‐biological model for U.S. east coast adjacent deep ocean that is nested within basin‐wide North Atlantic circulation order to estimate fluxes area Middle Bight (MAB). Our biological relatively simple representation processes water column organic matter remineralization at water‐sediment...
A new four-dimensional ocean interpolation system based on locally weighted least squares fitting is presented. loess filter used to interpolate irregularly spaced data onto a uniform grid. This involves projecting the quadratic functions of latitude and longitude while simultaneously annual semiannual harmonics by squares. The smoothness scale mapping method adapts match density, thus producing gridded estimates with maximum resolution. has vertical dimension, such that adjacent levels are...

We describe a new diabatic primitive equation model for studying regional and basin-scale ocean circulation processes. The features coordinate transformations that efficiently incorporate moderately irregular basin geometries large variations in bottom topography, permits the inclusion of both thermal wind forcing. A novel semi-spectral solution procedure, which vertical structure variables is represented as finite sum user-specifiable functions (e.g., Chebyshev polynomials), provides...
The Office of Naval Research's Coupled Boundary Layers and Air–Sea Transfer (CBLAST) program is being conducted to investigate the processes that couple marine boundary layers govern exchange heat, mass, momentum across air–sea interface. CBLAST-LOW was designed these at low-wind extreme where are often driven or strongly modulated by buoyant forcing. focus on conditions ranging from negligible wind stress, forcing dominates, up speeds wave breaking Langmuir circulations play a significant...
The contribution of coastal oceans to the global air‐sea CO 2 flux is poorly quantified due insufficient availability observations and inherent variability physical, biological chemical processes. We present simulated fluxes from a high‐resolution biogeochemical model for North American east coast continental shelves, region characterized by significant sediment denitrification. Decreased fixed nitrogen denitrification reduces primary production incorporation inorganic carbon into organic...

Coastal zones are highly dynamical systems triggered by a variety natural and anthropogenic forcing factors, that include sea level rise, extreme events, local oceanic atmospheric processes, ground subsidence, etc. However so far, they remain poorly monitored on global scale. To better understand changes affecting world coastal to provide crucial information decision-makers involved in adaptation mitigation of environmental risks, observations various types need be collected analyzed. In...
Abstract The Chesapeake Bay plays an important role in transforming riverine nutrients before they are exported to the adjacent continental shelf. Although mean nitrogen budget of has been previously estimated from observations, uncertainties associated with interannually varying hydrological conditions remain. In this study, a land‐estuarine‐ocean biogeochemical modeling system is developed quantify inputs, within‐estuary transformation processes and ultimate export coastal ocean. Model...
The paper gives an overview of the development satellite oceanography over past five years focusing on most relevant issues for operational oceanography. Satellites provide key essential variables to constrain ocean models and/or serve downstream applications. New and improved data sets have been developed directly quality products. status constellation last was, however, not optimal. Review future missions shows clear progress new research with a potentially large impact should be...
The Global Ocean Observing System (GOOS) and its partners have worked together over the past decade to break down barriers between open-ocean coastal observing, scientific disciplines, operational research institutions. Here we discuss some GOOS successes challenges from decade, present ideas for moving forward, including highlights of 2030 Strategy published in 2019. OceanObs'09 meeting Venice 2009 resulted a remarkable consensus on need common set guidelines global ocean observing...
A coastal ocean forecasting system was developed for the Long‐term Ecosystem Observatory (LEO) on New Jersey's inner shelf. The forecast comprised an model, Regional Ocean Modeling System, forced by a high‐resolution atmospheric forecast, with assimilation of data from ships and radar systems. forecasts were used to aid deployment real‐time adaptive sampling observing systems during July 2001 Coastal Predictive Skill Experiment. Temperature salinity prepared optimal interpolation shipboard...
[1] Meteotsunamis are oceanic waves that possess tsunami-like characteristics but meteorological in origin. In the western Mediterranean, travelling atmospheric pressure oscillations generate these long surface can become amplified and produce strong seiche inside harbors. We analyze a June 2006 meteotsunami event Ciutadella harbor (Menorca Island, Spain), studying numerically phenomenon during its full life cycle, from early stages to atmosphere-ocean resonant phase final highly...
Prescribing open boundary conditions for regional coastal ocean models encounters the challenge of imposing information on sea level, velocity and tracers that characterize unrepresented far field ocean. Deriving such from a larger domain model without communicating “nested” back to exterior is “downscaling”. We evaluate whether real‐time presently in operation Mid‐Atlantic Bight (MAB) can deliver useful predictions subtidal frequency currents subsurface temperature salinity this downscaling...
Recent advances in Coastal Ocean Forecasting Systems (COFS) are discussed. Emphasis is given to the integration of observational and modeling components, each developed context monitoring forecasting coastal seas. These integrated systems must be linked larger scale toward seamless data sets, nowcasts forecasts (from global ocean, through continental shelf nearshore regions). Emerging capabilities include: methods optimize coastal/regional networks; probabilistic approaches address both...
Operational ocean forecast systems provide routine marine products to an ever-widening community of users and stakeholders. The majority need information about the quality reliability exploit them fully. Hence, centres have been developing improved methods for evaluating communicating their products. Global Ocean Data Assimilation Experiment (GODAE) OceanView, along with Copernicus European Marine Core Service other national international programmes, has facilitated development coordinated...

Developing enduring capacity to monitor ocean life requires investing in people and their institutions build infrastructure, ownership, long-term support networks. International initiatives can enhance access scientific data, tools methodologies, develop local expertise use them, but without ongoing engagement may fail have lasting benefit. Linking development technology transfer sustained monitoring is a win-win proposition. Trained experts will benefit from joining global communities of...

Ocean surface circulation can be estimated by automated tracking of thermal infrared features in pairs sequential satellite imagery. A 7-yr time series velocity, extracted from imagery the East Australian Current using maximum cross-correlation (MCC) technique, provides enough measurements for a more statistical evaluation method than has previously been possible. Excluding 1 yr with extensive cloud cover, produces about 8000 velocity estimates per month some seasonal variation. Method...
