Temporal variability of gas seeps offshore New Zealand: Multi-frequency geoacoustic imaging of the Wairarapa area, Hikurangi margin [PDF]

, 2008
Cold seeps of the Wairarapa area situated around 1000 metres water depth on the Hikurangi margin offshore New Zealand’s North Island have been investigated using multibeam bathymetry, 75 and 410 kHz sidescan sonar imagery as well as 2-8 kHz Chirp ...

Chemotrophic Microbial Mats and Their Potential for Preservation in the Rock Record [PDF]

, 2009
Putative microbialites are commonly regarded to have formed in association with photosynthetic microorganisms, such as cyanobacteria. However, many modern microbial mat ecosystems are dominated by chemotrophic bacteria and archaea.

A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

Journal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

Near Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

MICROORGANISMS OF MARINE COLD HYDROCARBON SEEPS

Microbiology&Biotechnology
Marine hydrocarbon seeps, due to their unique geophysical and geochemical characteristics, form unique conditions for the development of specific microbial communities. Diverse and interconnected metabolic activities of them underlie global ecological processes. In this review were considered the geophysical and chemical conditions for the formation of

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...
