چکیده

Monitoring the dynamics of marginal oceanic systems remains a complex and challenging task, owing to the wide spectrum of spatial and temporal scales of the oceanic processes occurring there. On one hand, sustained in situ observations are generally too sparse in coastal areas despite the development of initiatives by international programs. On the other hand, remote sensing techniques for routinely monitoring of the sea surface (e.g. radar altimetry, SST, ocean color) encounter intrinsic limitations when moving near coasts due to the fact that they are designed with open ocean in mind and in most cases do not account for specificities of the coastal zone (presence of land, of clouds, inappropriate processing, etc.). In the coastal zone, an integrated approach merging in situ, remote sensing and model data should be preferred, in particular by adopting improved (reprocessed) coastal altimeter data: this is one of the central objectives of the MARINA (MARgin INtegrated Approach) project funded by CNES within the Ocean Surface Topography Science Team (OST-ST) framework.

Tidal prediction using time series analysis of Buoy observations

Although tidal observations which are extracted from coastal tide gages, have higher accuracy due to their higher sampling rate, installing these types of gages can impose some spatial limitation since we cannot use every part of sea to install them. To solve this limitation, we can employ satellite altimetry observations. However, satellite altimetry observations have lower sampling rate. Acco...

Monitoring Sea Level in the Coastal Zone with Satellite Altimetry and Tide Gauges

We examine the issue of sustained measurements of sea level in the coastal zone, first by summarizing the long-term observations from tide gauges, then showing how those are now complemented by improved satellite altimetry products in the coastal ocean. We present some of the progresses in coastal altimetry, both from dedicated reprocessing of the radar waveforms and from the development of imp...

SPREAD OF THE GLUCOSE-6-PHOSPHATE DEHYDROGENASE VARIANT (G6PD-MEDITERRANEAN) IN ONE OF THE COASTAL PROVINCES OF CASPIAN SEA IN IRAN

In order to explore the nature of glucose-6-phosphate dehydrogenase (G6PD) deficiency in one of the coastal provinces of the Caspian Sea (Mazandaran) in Iran, we have analysed the G6PD gene in 74 unrelated G6PD-deficient males (2-6 year children) with a history of Favism, by using PCR and subsequent digestion by appropriate restriction enzymes, looking for the presence of certain known mutation...

Gravity acceleration at the sea surface derived from satellite altimetry data using harmonic splines

Gravity acceleration data have grand pursuit for marine applications. Due to environmental effects, marine gravity observations always hold a high noise level. In this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. On the one hand, harmonic spline functions have great capability for local gravity ...

Improvement of coastal and mesoscale observation from space: Application to the northwestern Mediterranean Sea

[1] We present an innovative approach to the generation of remotely sensed high-resolution sea surface topography that improves coastal and mesoscale dynamic characterization. This new method is applied for the period 2002–2010 in the northwestern Mediterranean Sea, an area marked by a small Rossby radius. The spectral content of the new mapped data is closer to that of the along-track signal a...
