this study reports the concentrations of important tracers of the marine environment, 210po and210pb, in different matrices from field samples collected at central adriatic sea (italy), a non-contaminatedmarine ecosystem. 210po concentration appears to decrease with increasing distance from the coast and asignificant difference in 210po concentrations in seawater samples at two different depths...

in this research, the correlation between precipitation change in southern coasts of caspian sea and variability of sea level pressure have been analyzed by using environmental to circulation approach at time period 1339- 1383. in this respect, we make use of daily precipitation data of the 12 synoptic stations of studied area at surface data base section and prepare the time series matrix of p...

Relative sea-level changes during the last w2500 years in New Jersey, USA were reconstructed to test if late Holocene sea level was stable or included persistent and distinctive phases of variability. Foraminifera and bulk-sediment d13C values were combined to reconstruct paleomarsh elevation with decimeter precision from sequences of salt-marsh sediment at two sites using a multi-proxy approac...

Interactions with sea turtles have occurred at an alarming rate in swordfish longlining in Hawaii in recent years and various regulations have been put forward to protect sea turtles. In order to understand the cost of reducing sea turtle interactions, methods have been developed to derive the shadow price of sea turtle bycatch based on fisher's welfare loss from a specific regulation. This pap...

summer heat and drought conditions, especially in the southern half of iran's air sovereignty is recognized. in order to investigate the synoptic conditions - scanning the effect of unusual rain event for summer 12 to 6 september 2008 (22-16 september 1387) in the southern zagros range, environmental approach to sightseeing and daily statistics recording station 270 days of rain detected. ...

We present new sea-level reconstructions for the past 2100 y based on salt-marsh sedimentary sequences from the US Atlantic coast. The data from North Carolina reveal four phases of persistent sea-level change after correction for glacial isostatic adjustment. Sea level was stable from at least BC 100 until AD 950. Sea level then increased for 400 y at a rate of 0.6 mm/y, followed by a further ...
