Existing methods to predict the effects of climate change on biomass and production marine communities are predicated modelling interactions dynamics individual species, a very challenging approach when distributions changing little is known about ecological mechanisms driving responses many species. An informative parallel develop size-based methods. These capture properties food webs that describe energy flux at particular size, independent species' ecology. We couple...
Electron densities retrieved from the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) radio occultation (RO) measurements are compared with those measured by incoherent scatter radars (ISR) ionosondes in this paper. These results show that electron density profiles COSMIC RO data agreement ISR ionosonde measurements. The ionospheric characteristics ( N m F 2 h ) derived satellites also calculated latest International Reference Ionosphere model (IRI‐2001)...

Abstract Harmful algal blooms ( HAB s), those proliferations of algae that can cause fish kills, contaminate seafood with toxins, form unsightly scums, or detrimentally alter ecosystem function have been increasing in frequency, magnitude, and duration worldwide. Here, using a global modeling approach, we show, for three regions the globe, potential effects nutrient loading climate change two genera, pelagic Prorocentrum Karenia , each differing physiological characteristics growth. The...
Abstract Ocean warming can modify the ecophysiology and distribution of marine organisms, relationships between species, with nonlinear interactions ecosystem components potentially resulting in trophic amplification. Trophic amplification (or attenuation) describe propagation a hydroclimatic signal up food web, causing magnification depression) biomass values along one or more pathways. We have employed 3‐D coupled physical‐biogeochemical models to explore responses climate change focus on...
We present a global view of large‐scale ionospheric disturbances during the main phase major geomagnetic storm. find that low‐latitude, auroral, and polar latitude regions are coupled by processes redistribute thermal plasma throughout system. For large storm on 20 November 2003, we examine data from high‐latitude incoherent scatter radars at Millstone Hill, Sondrestrom, EISCAT Tromso, with SuperDARN HF radar observations convection pattern DMSP in situ parameters topside ionosphere. combine...
A precipitation index is described which quantifies the intensity and spatial extent of high‐latitude particle based on observations made along individual satellite passes. By sorting plasma convection data according to this index, average patterns ionospheric electric field have been derived from a set consisting five years' by Millstone Hill radar. Reference instantaneous keyed it, provides means characterizing global throughout an event.
The Proudman Oceanographic Laboratory Three‐Dimensional Baroclinic B grid model (POL3DB) has been developed to incorporate features suitable for the modeling of baroclinic processes on shelf, at shelf slope, and in ocean regions allow long‐term coupled ocean‐shelf simulations. We test northwest European continental period November 1988 October 1989 against satellite sea surface temperature measurements, CTD sections both off (in summary) whole North Sea Project data set. accurately...
A new operational ocean forecast system, the Atlantic Margin Model implementation of Forecast Ocean Assimilation (FOAM-AMM), has been developed for European North West Shelf (NWS). An overview system is presented including shelf specific developments physical model, Nucleus Modelling (NEMO), and Sea Surface Temperature (SST) data assimilation scheme. Initial validation tides model SST. The SST skill significantly improved by Finally, an analysis seasonal tidal mixing fronts shows that these,...

Abstract. Accurately representing coastal and shelf seas in global ocean models represents one of the grand challenges Earth system science. They are regions immense societal importance through goods services they provide, hazards pose their role global-scale processes cycles, e.g. carbon fluxes dense water formation. However, poorly represented current generation models. In this contribution, we aim to briefly characterise problem, then identify important physical processes, scales, needed...
Abstract. In this paper we clearly demonstrate that changes in oceanic nutrients are a first order factor determining the primary production of northwest European continental shelf on time scales 5–10 yr. We present series coupled hydrodynamic ecosystem modelling simulations, using POLCOMS-ERSEM system. These forced by both reanalysis data and single example ocean-atmosphere general circulation model (OA-GCM) representative possible conditions 2080–2100 under an SRES A1B emissions scenario,...

Regional seas are potentially highly vulnerable to climate change, yet the most directly societally important regions of marine environment. The combination widely varying conditions mixing, forcing, geography (coastline and bathymetry) exposure open-ocean makes these subject a wide range physical processes that mediates how large scale change impacts on seas' ecosystems.

Abstract Efforts to manage living marine resources (LMRs) under climate change need projections of future ocean conditions, yet most global models (GCMs) poorly represent critical coastal habitats. GCM utility for LMR applications will increase with higher spatial resolution but obstacles including computational and data storage costs, obstinate regional biases, formulations prioritizing robustness over skill persist. Downscaling can help address limitations, significant improvements are...
Transports across the continental shelf edge enhance shelf-sea production, remove atmospheric carbon and imply an active boundary to ocean circulation. We estimate relatively large overall transport three contrasted sectors of north-west European edge: Celtic Sea south-west Britain, Malin-Hebrides west Scotland, West Shetland north Scotland. The estimates derive from measurements in project FASTNEt (Fluxes sloping topography North East Atlantic): drifters, moored current meters, effective...
A joint alert campaign was organized during the month of October 1980 by incoherent scatter radars in American sector: namely, Jicamarca, Arecibo, Millstone Hill, and Chatanika. The campaign, which met with success, designed to study behavior ionospheric electric field as a function latitude magnetically active conditions. Arecibo data this support present previous observations at Jicamarca that suggest when convection E suddenly decreases, Alfvén layer shielding becomes unbalanced...
