Dispersal of marine benthic invertebrates through ice rafting.
Knowledge of dispersal vectors used by organisms is essential to the understanding of population and community dynamics. We report on ice rafting, a vector by which intertidal benthic invertebrates can be transported well outside their normal dispersal range during winter in temperate climates. We found multiple invertebrate taxa in sediment-laden ice blocks sampled in the intertidal zone. A la...
متن کاملThermodynamics of an Ice Age: The Cause and Sequence of Glaciation.
The Fisher Burner produces an intensly hot flame for all types of laboratory heating operations including many ignitions and incinerations which otherwise would require the use of compressed air. Instead of the cold cone and hot tip characteristic of the Bunsen flame, the Fisher flame is short and wide and is uniformly hot throughout.
متن کاملEvidence for an ice shelf covering the central Arctic Ocean during the penultimate glaciation
The hypothesis of a km-thick ice shelf covering the entire Arctic Ocean during peak glacial conditions was proposed nearly half a century ago. Floating ice shelves preserve few direct traces after their disappearance, making reconstructions difficult. Seafloor imprints of ice shelves should, however, exist where ice grounded along their flow paths. Here we present new evidence of ice-shelf grou...
متن کاملFrom Ice to Ice-free: Glaciation in the Lake Ayr Valley, Central Tasmania
During the Last Glaciation in Tasmania a large ice cap developed on the western edge of the Central Plateau and overlapped on to the Cradle Mountain-Lake St Clair area. Several reticulate lobes flowed from this source, with the largest northern outlet, the Mersey Glacier, covering an area of c. 282 km2• The Lake Ayr Valley was occupied by a smail diffiuent lobe of the Mersey Glacier, and the la...
متن کاملClimate and groundwater recharge during the last glaciation in an ice-covered region
A multitracer study of a small aquifer in northern Switzerland indicates that the atmosphere in central Europe cooled by at least 5 degreesC during the last glacial period. The relation between oxygen isotope ratios (delta18O) and recharge temperatures reconstructed for this period is similar to the present-day one if a shift in the delta18O value of the oceans during the ice age is taken into ...
