Steroid estrogens in ocean sediments.
This paper gives results from a study measuring the abundance of steroid hormones in ocean sediments in the proximity of a deep ocean sewage outfall. The outfall is discharge point for an enhanced primary sewage treatment plant and sediment samples were taken adjacent and 7 km from the outfall. All samples contained steroid estrogens at nanogram per gram levels with higher concentrations at the...
متن کاملTemporal-Spatial Variability of the Severest Dry Spells in the North-West of Iran
The variability of temperature and precipitation is regarded as one of the main characteristics of the climate.Precipitation and its results, especially results such as droughts, vary on different temporal and spatial scales. Thepurpose of this paper is to determine the frequency of the inter-annual variability of the driest month in north-westIran. In order to obtain the best results, we used ...
متن کاملHigh-Frequency Sound Interaction in Ocean Sediments
Our long-term goal is to develop accurate models for high-frequency scattering from, penetration into, and propagation within shallow water sediments. Reaching this goal requires a better understanding of several fundamental issues pertinent to high-frequency sediment acoustics. These issues include an understanding of the dominant scatterers versus frequency near the sediment surface, the pote...
متن کاملA synoptic study on seasonal patterns of wet and dry spells in midwest of Iran
The effective patterns and mechanisms of synoptic systems during the wet and dry spells in Midwest of Iran(MWI) analyzed and discussed on seasonal scales from 1974 to 2003. Synoptic Analysis is based on synoptic chartson Sea Level Pressure (SLP), 850 and 500 Hpa levels. The results of synoptic analysis show that dry spells in MWIare mostly corresponded to Azores High (AZH) intensifying and its ...
متن کاملWarm and Dry Spells (WDS) in Austral Winter over Central South America
The horizontal and vertical structure of unusually warm and dry spells (WDS) over the central parts of South America during the winter and post-winter months (JJAS) are studied. During WDS the mean temperature and humidity anomalies over central Brazil are about +4.1C and −13.2%, respectively. The mean duration of WDS is 11 days and their mean frequency is less than one per year during the mont...
