An effective method is presented for determining the ozone (O3) mixing ratio in the onshore flow of marine air at the North American west coast. By combining the data available from all marine boundary layer (MBL) sites with simultaneous wind data, decadal temporal trends of MBL O3 in all seasons are established with high precision. The average springtime temporal trend over the past two decade...

STOCK DEFINITION AND GEOGRAPHIC RANGE The harp seal occurs throughout much of the North Atlantic and Arctic Oceans (Ronald and Healey 1981; Lavigne and Kovacs 1988); however, in recent years, numbers of sightings and strandings have been increasing off the east coast of the United States from Maine to New Jersey (Katona et al. 1993; Stevick and Fernald 1998; B. Rubinstein, pers. comm., New Engl...

Seagrass beds are the largest organism-built marine habitat in Dominica, yet have only been surveyed since 2007. Standardized examinations along a depth gradient between 0 and 24 m, focusing on magnoliophyte species composition and benthic cover of shoots at 17 seagrass bed sites, were carried out between September 10 and December 7, 2008. The Cymodoceaceae Syringodium filiforme (Kuetzing 1860)...

The coastal morphotype is continuously distributed along the Atlantic coast south of Long Island, around peninsula Florida and along the Gulf of Mexico coast. On the basis of differences in mtDNA haplotype frequencies, however, Curry (1997) concluded that the nearshore animals in the northern Gulf of Mexico and the western North Atlantic were significantly different and represent separate stock...

the hazardous effect of heavy metals on the histopathology of selected organs of the freshwater fish common carp (cyprinus carpio l.) was investigated. gill, liver, kidney and flesh samples were collected after 32 days of exposure to a sublethal concentration of 5 mg/l of combined (cd + pb + cr + ni) metal solution containing 1.25 mg/l of each metal ion (1/10th of lc50 / 48h) was analyzed by us...

This article suggests a second thought on two papers published in Cognitive psychology in 1978 and 1981. Both articles deal with systematic distortions in cognitive mapping and both are based on experiments conducted along the North American West Coast. The first, by Stevens and Coupe, deals with distortions due to hierarchical organization while the second, by Tversky, with distortions due to ...
