Changing atmospheric conditions may contribute to stronger ocean wave activity on the Antarctic Peninsula（图）
Changing atmospheric conditions stronger ocean wave activity Antarctic Peninsula
2017/2/16
Over the past few years, a large fracture has grown across a large floating ice shelf on the Antarctic Peninsula. The world is watching the ice shelf, now poised to break off an iceberg the size of De...
HANDS-ON OCEANOGRAPHY | Corals on Acid: An Inquiry-based Activity Leading Students to a Better Understanding of Ocean Acidification Impacts
Ocean sea creatures calcification invertebrate animal bones calcium carbonate
2015/7/16
The objective of this inquiry-based lesson is for students to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms. During this activity, students: (1...
HANDS-ON OCEANOGRAPHY | A Classroom Activity Using Satellite Sea Surface Temperatures to Predict Coral Bleaching
HANDS-ON OCEANOGRAPHY Satellite Sea Surface Temperatures Predict Coral Bleaching

Shifts in limiting nutrients in an estuary caused by mixing and biological activity
limiting nutrients mixing biological activity
2014/4/8
Simple general equations are used to show that when riverine water mixes with seawater, the N : P ratio is a
nonlinear function of salinity. Thus, a shift in the limiting-nutrient status at a particu...
Characterization of alkaline phosphatase activity in the North and South Pacific Subtropical Gyres: Implications for phosphorus cycling
alkaline phosphatase activity iin the North South Pacific Subtropical Gyres:phosphorus cycling
2014/4/8
We characterized alkaline phosphatase (AP) activity (APA) and report AP kinetic parameters in the North and South Pacific Subtropical Gyres (NPSG and SPSG, respectively) to evaluate the relative impor...
Phosphatases relieve carbon limitation of microbial activity in Baltic Sea sediments along a redox-gradient
carbon limitation Baltic Sea sediments
2014/4/4
The relationship between phosphatase activity and the element limiting microbial activity (carbon [C], nitrogen
[N], or phosphorus [P]) was studied experimentally in sediment from four stations in th...
Abundance and single-cell activity of bacterial groups in Antarctic coastal waters
Abundance single-cell activity
2014/4/17
We estimated the abundance and single-cell activity of bacterial groups in waters off the West Antarctic
Peninsula (WAP) using a combination of microautoradiography and fluorescent in situ hybridizat...
Unraveling the role of land use and microbial activity in shaping dissolved organic matter characteristics in stream ecosystems
role of land use microbial activity in shaping dissolved organic matter in stream ecosystems
2014/4/17
Surface water samples were collected from 43 streams distributed throughout watersheds of mixed land use in southern Ontario, Canada. Absorbance and fluorescence spectroscopy with parallel factor anal...
Living at the border: A community and single-cell assessment of lake bacterioneuston activity
Living at the border A community single-cell assessment lake bacterioneuston activity
2014/4/17
We assessed the physicochemical properties of the surface microlayer (SML: first 900mm) and its underlying water (ULW: 0.2–0.5-m depth) and compared the composition and activity of their bacterial com...
Alkaline phosphatase activity and regulation in the North Pacific Subtropical Gyre
Alkaline phosphatase activity regulation the North Pacific Subtropical Gyre
2014/4/17
Alkaline phosphatase (AP) activity (APA) was measured at several stations in the North Pacific Subtropical Gyre in July 2008, and in a series of nutrient addition experiments: nitrate plus ammonium (+...
Spatiotemporal distribution and activity patterns of bacteria from three phylogenetic groups in an oligomesotrophic lake
Spatiotemporal distribution an oligomesotrophic lake
2014/4/16
We explored the seasonal and vertical patterns of cell numbers, biomass, and amino acid incorporation of three
major phylogenetic groups of the bacterioplankton in an oligomesotrophic alpine lake. Th...

Simultaneous determination of in situ vertical transitions of color, pore-water metals, and visualization of infaunal activity in marine sediments
Simultaneous situ vertical transitions of color
2014/4/17
The vertical color transition from brown to gray-green in marine sediments is linked to the Fe redox boundary
and is commonly used as a proxy for biogeochemical state. We combine time-lapse sediment ...
