A growing number of studies are concluding that the resilience Arctic sea ice cover in a warming climate is essentially controlled by its thickness. Satellite radar and laser altimeters have allowed us to routinely monitor thickness across most Ocean for several decades. However, key uncertainty remaining retrieval error on surface height (SSH) which conventionally interpolated at floes from li...

The vertical (altitudes at 0.1; 0.3; 0.6; 0.9 and 1.2 m above mean sea level - MSL) distribution of Cyanobacteria in the supralittoral zone Cape Kilse-Burun (Meganom Peninsula) was characterized. A total 20 species have been recorded; their number various altitudes varied from 6 to 9 (minimal MSL). As for systematic composition, Oscillatoriophycidae subclass were found on entire range altitudes...

Arctic sea surface height (SSH) is poorly observed by radar altimeters due to the poor coverage of the polar oceans provided by conventional altimeter missions and because large areas are perpetually covered by sea ice, requiring specialized data processing. We utilize SSH estimates from both the icecovered and ice-free ocean to present monthly estimates of Arctic Dynamic Ocean Topography (DOT)...

An empirical approach is presented for the estimation of the partial pressure of carbon dioxide (pCO2) and air–sea CO2 fluxes in the northern South China Sea in summer using satellite-derived sea surface temperatures (SSTs), chlorophyll-a (Chl a) concentrations, and wind fields. Two algorithms were tested. The first used an SST-dependent equation, and the other involved the introduction of Chl ...

[1] Sea surface height (SSH) measurements from the Geosat satellite altimetry mission are analyzed to statistically characterize their noise process, which is defined here as the small-scale (<50 km), timevarying component of the altimetry data. This analysis is one component of a larger effort to extract meaningful information about seafloor roughness from the small-scale fabric of the altimet...

[1] In this study, we extend the advanced approach of combining tide gauge and satellite altimetry data with supplemental equations from adjacent tide gauge records of at least 30 years of common data to investigate the relative importance of the nonclimate contribution of vertical land movement to the observed rates of sea level change along the coasts of southern Europe. The sensitivity tests...

James R. Slusser, MEMBER SPIE Colorado State University Natural Resources Ecology Laboratory Fort Collins, Colorado 80521 Abstract. Global atmospheric trends in ozone column amount have focused attention on the environmental risk of exposure to ultraviolet (UV) radiation. Monitoring UV irradiance in diverse and remote locations is necessary to understand the variability of exposure, dose rates,...

Only approximately 20% of the global seafloor topography has been finely modeled. The rest either lacks data or its are not accurate enough to meet practical requirements. On one hand, satellite altimeter advantages large-scale and real-time observation. Therefore, it is widely used measure bathymetry, core topography. However, there often room improve precision. Multibeam sonar bathymetry more...

The determination of high-quality mean dynamic topography (MDT) over island areas faces multiple challenges, due to the error in a global geopotential model (GGM) as well contaminated waveforms satellite altimetry data and scarcity surveyed gravimetric observations. We study potential enhance regional quasi-geoid/MDT by using recently released altimetric gravity airborne Numerical experiments P...
