On the Movement of Beluga Whales in Cook Inlet,Alaska:Simulations of Tidal and Environmental Impacts Using a Hydrodynamic Inundation Model
Beluga Whales Cook Inlet Alaska Tidal and Environmental Hydrodynamic Inundation Model
2015/7/22
The population of beluga whales in Cook Inlet, Alaska, is in decline, and since 2000 these whales have been under consideration for designation as "endangered" under the Endangered Species Act (and we...
Remote Detection of Marine Microbes,Small Invertebrates,Harmful Algae,and Biotoxins using the Environmental Sample Processor (ESP)
Marine Microbes Small Invertebrates Harmful Algae Biotoxins using the Environmental Sample Processor

Environmental constraints invasive Mnemiopsis leidyiin Scandinavian waters
2014/4/2
We studied the seasonal dynamics of the invasive ctenophoreMnemiopsis leidyiover its distribution range from Skagerrak into the Baltic Proper during 1 yr and related this to ambient physical and biolo...
Fine spatial structure of genetically distinct picocyanobacterial populations across environmental gradients in the Costa Rica Dome
Fine spatial structure genetically distinct picocyanobacterial populations across environmental gradients in the Costa Rica Dome
2014/4/2
We investigated the spatial variability of picocyanobacterial community structure across the Costa Rica Dome(CRD), an offshore upwelling system characterized by high seasonal abundance of Synechococcu...

2014/4/2
Biogenic dimethylsulfide (DMS) and its main precursors, dimethylsulfoniopropionate (DMSP) and dimethylsulfoxide (DMSO), are potential scavengers of reactive oxygen species in marine algae, and these d...
Hypersaline waters pose new challenges for reconstructing environmental histories of fish based on otolith chemistry
Hypersaline waters pose new challenges reconstructing environmental histories fish based otolith chemistry
2014/4/4
We investigated the effect of hypersaline conditions on the water chemistry of the Coorong Lagoon, the terminal estuary of Australia's largest river, and the otolith chemistry of a common fish within ...
Spatial distribution of intact polar lipids in North Sea surface waters: Relationship with environmental conditions and microbial community composition
Spatial distribution intact polar lipids North Sea surface waters Relationship with environmental conditions microbial community composition
2014/4/3
We characterized and quantified the intact polar lipid (IPL) composition of the surface waters of the North Sea and investigated its relationships with environmental conditions, microbial abundances, ...
Effects of environmental conditions on the seasonal distribution of phytoplankton biomass in the North Sea
environmental conditions the seasonal distribution phytoplankton biomass in the North Sea
2014/4/18
We study the spatial and seasonal variability of phytoplankton biomass (as phytoplankton color) in relation to the environmental conditions in the North Sea using data from the Continuous Plankton Rec...
Environmental control of open-ocean phytoplankton groups: Now and in the future
Environmental control open-ocean phytoplankton groups Now and in the future
2014/4/17
Climate change will alter concurrently many environmental factors that exert control over oceanic phytoplankton. Recent laboratory culture work, shipboard experiments, and field surveys reveal many re...
Genetic and environmental factors influence survival and hatching of diapausing eggs
environmental factors Genetic diapausing eggs
2014/4/16
To test the hypothesis that variation in hatching and survival of Daphnia dormant eggs is fostered by genetic
differences among populations, rather than system-specific availability of environmental ...
