Markov Models For Linking Environments And Facies In Space And Time (Recent Arabian Gulf, Miocene Paratethys), Bernhard Riegl, Samuel J. Purkis

Marine & Environmental Sciences Faculty Articles

If, as comparative sedimentology maintains, knowledge of the Recent can sometimes be helpful to explain the past (and vice-versa), common quantitative denominators might exist between Recent and fossil systems. It may also be possible to describe dynamics and find linkages between space and time with a unique set of quantitative tools. To explore such conceptual links, spatial facies patterns mapped using satellite imagery were compared with temporal patterns in analogous ancient outcropping facies using Markov chains and graphs. Landsat and Ikonos satellite imagery was used to map benthic facies in a nearshore carbonate ramp (Ras Hasyan) and offshore platform system …

Dms Air/Sea Flux And Gas Transfer Coefficients From The North Atlantic Summertime Coccolithophore Bloom, Christa Marandino, Warren J. De Bruyn, Scott Miller, Eric S. Saltzman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Dimethylsulfide (DMS) atmospheric and oceanic concentrations and eddy covariance air/sea fluxes were measured over the N. Atlantic Ocean during July 2007 from Iceland to Woods Hole, MA, USA. Seawater DMS levels north of 55 degrees N ranged from 3 to 17 nM, with variability related to the satellite-derived distributions of coccoliths and to a lesser extent, chlorophyll. For the most intense bloom region southwest of Iceland, DMS air/sea fluxes were as high as 300 mu mol m(-2) d(-1), larger than current model estimates. The observations imply that gas exchange coefficients in this region are significantly greater than those estimated using …

Differential Expression Of Immune Response Genes In Steller Sea Lions (Eumetopias Jubatus): An Indicator Of Ecosystem Health?, Lizabeth Bowen, Brian Aldridge, Kimberlee Beckmen, Tom Gelatt, Lorrie Rea, Kathy Burek, Ken Pitcher, Jeffrey L. Stott

United States Department of Commerce: Staff Publications

Characterization of the polygenic and polymorphic features of the Steller sea lion major histocompatibility complex (MHC) provides an ideal window for evaluating immunologic vigor of the population and identifying emergence of new genotypes that reflect ecosystem pressures. MHC genotyping can be used to measure the potential immunologic vigor of a population. However, since ecosystem-induced changes to MHC genotype can be slow to emerge, measurement of differential expression of these genes can potentially provide real-time evidence of immunologic perturbations. MHC DRB genes were cloned and sequenced using peripheral blood mononuclear leukocytes derived from 10 Steller sea lions from southeast Alaska, Prince …

Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Of the four time of planting trials twodefinitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 and …

Experimental Summaries - Plant Research

Results from trials comparing the growth and persistence of a number of annual pasture legumes in 1973 are presented in this report. Rainfall conditions during the year are described briefly and a table of annual and growing season rainfall at relevant centres is appended. The experiments are grouped as follows according to average annual rainfall:- Zone A - Average annual rainfall 400 mm. Zone B - Average annual rainfall 345 - 400 mm. Zone C - Average annual rainfall 345 mm. and then further on soil type. 70GE4, 70ME3, 70ME4, 70NA3, 70TS2, 70TS5, 71LG16, 71TS22, 72LG3, 72LG26,

1973 Rates Of Phosphate On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Comments on Results - New Land sites (Graphs 1, 2) - The three sites were very responsive with the point of inflexion about 600 kg/ha super rate (similar to 1972 result). The seed x super rate interaction shows the quicker response to super with higher seeding rates. Low Super Bank (800 kg/ha) (GRAPH 3) - The two sites showed very little response to super applied. On the Eradu sandplain no response to super for either Unicrop or Wheat. On the Watheroo yellow sandplain (73M015) the two lupin cultivers and the wheat gave different responses. High Super Bank (>1 OOOkg/ha) …
