Anthropogenic semivolatile organic compounds (SOCs) that persist in the environment, bioaccumulate, are toxic at
low concentrations, and undergo long-range atmospheric transport (LRT) were identified and quantified in the atmosphere
of a Saharan dust source region (Mali) and during Saharan dust incursions at downwind sites in the eastern
Caribbean (U.S. Virgin...

Research mentorship is a new construct emerging in the literature, but remains inadequately defined and scarcely researched. This topic is of relevance to counselor education because of the paucity of literature on the topic, and because of our professional commitments to diversity, wellness, and scholarship. Effective mentorship has been shown...

The reason for the initial rise in atmospheric
CO₂ during the last deglaciation remains unknown. Most recent
hypotheses invoke Southern Hemisphere processes such
as shifts in midlatitude westerly winds. Coeval changes in
the Atlantic meridional overturning circulation (AMOC) are
poorly quantified, and their relation to the CO₂ increase is
not...

Remote aquatic ecosystems are exposed to an assortment of semivolatile organic compounds (SOCs) originating from current and historic uses, of local and global origin. Here, a representative suite of 57 current- and historic-use pesticides, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons were surveyed in the plasma of the western pond turtle...

Duplex stainless steels are desirable for use in power generation systems because of their attractive combination of strength, corrosion
resistance and cost. However, thermal embrittlement at intermediate homologous temperatures of ~475 °C and below, limits upper service temperatures
for many applications. New lean grade duplex alloys have improved thermal stability...

Air was sampled from the porous firn layer at the NEEM site in Northern Greenland. We use an ensemble of ten reference tracers of known atmospheric history to characterise the transport properties of the site. By analysing uncertainties in both data and the reference gas atmospheric histories, we can objectively...

Western North Pacific gray whales (WGWs), once considered extinct, are critically endangered with unknown migratory routes and reproductive areas. We attached satellite-monitored tags to seven WGWs on their primary feeding ground off Sakhalin Island, Russia, three of which subsequently migrated to regions occupied by non-endangered eastern gray whales (EGWs). A...

Individuals within populations often differ substantially in habitat use, the ecological consequences of which can be far reaching. Stable isotope analysis provides a convenient and often cost effective means of indirectly assessing the habitat use of individuals that can yield valuable insights into the spatiotemporal distribution of foraging specialisations within...

Considerable uncertainties often surround the causes of long-term changes in population abundance. One striking example is the precipitous decline of southern sea lions (SSL; Otaria flavescens) at the Falkland Islands, from 80 555 pups in the mid 1930s to just 5506 pups in 1965. Despite an increase in SSL abundance over...
