Heart Monitors On Wild Narwhals Reveal Alarming Responses To Stress（图）
Heart Monitors Wild Narwhals Alarming Responses Stress
2017/12/19
Narwhals released after entanglement in nets and outfitted with heart monitors performed a series of deep dives, swimming hard to escape, while their heart rates dropped to unexpectedly low levels of ...
Oceanographic Responses to Climate in the Northwest Atlantic
Oceanographic Responses Climate Northwest Atlantic
2015/8/4
Situated in an oceanographic transition zone, the Gulf of Maine~Western Scotian Shelf (GOM/WSS) region of the Northwest Atlantic is especially susceptible to changes in the climate system. Recent stud...
Biological Responses in a Dynamic Buoyant River Plume
Biological Responses Dynamic Buoyant River Plume
2015/7/22
Buoyant river plumes are highly dynamic and often characterized by marked physical and chemical gradients that interact to drive biological responses. For example, interactions among factors resulting...
Modeling Physical-Biological Responses to Climate Change in the California Current System
Climate Changel California Current System
2015/7/16
Understanding the effects of climate change on planktonic ecosystems requires the synthesis of large, diverse data sets of variables that often interact in nonlinear ways. One fruitful approach to thi...
Biogeochemical Responses in the Southern East China Sea After Typhoons
Biogeochemical Southern East China Sea Typhoons
2015/7/13
To understand the biogeochemical impact of typhoons in marginal seas, 16 sea-going expeditions were conducted from 2007 to 2009, covering all four seasons and including periods following the passage o...
Comparative responses of two dominant Antarctic phytoplankton taxa to interactions between ocean acidification, warming, irradiance, and iron availability
ocean acidification warming irradiance
2014/11/28
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis
antarctica (a prymnesiophyte) and Fragilariopsis cylindrus(a diatom) to a clustered matrix of th...

2014/10/16
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis antarctica (a prymnesiophyte) and Fragilariopsis cylindrus (a diatom) to a clustered matrix of th...
The responses of eight coral reef calcifiers to increasing partial pressure of CO2 do not exhibit a tipping point
The responses eight coral reef calcifiers increasing partial pressure CO2 do not exhibit a tipping point
2014/4/2
The objective of this study was to investigate whether a tipping point exists in the calcification responses of coral reef calcifiers to CO2. We compared the effects of six partial pressures of CO2(PC...
Physical responses of small temperate lakes to variation in dissolved organic carbon concentrations
dissolved organic carbon concentrations lakes
2014/4/2
We used a mechanistic physical model to examine the effect of variability in dissolved organic carbon (DOC)
concentrations on the physical properties of small temperate lakes. The model was validated...
Responses to iron limitation in two colonies of Stylophora pistillata exposed to high temperature: Implications for coral bleaching
Stylophora pistillata Responses coral bleaching
2014/4/8
Exposing the coral Stylophora pistillata to seawater depleted in available iron by complexation with the strong
chelator desferrioxamine B reduces the photosynthetic efficiency and alters the pigment...
Time-domain Analysis of FPSO-tanker Responses in Tandem Offloading Operation
FPSO tanker tandem offloading time-domain simulation
2011/9/9
Problems experienced during Floating Production, Storage and Offloading (FPSO) tandem offloading operations were investigated. The aim of this research was to improve the reliability of such systems, ...
Coexisting overwintering strategies inDaphnia pulex: A test of genetic differences and growth responses
Coexisting overwintering strategies in Daphnia pulexp A test of genetic differences growth responses
2014/4/16
We tested whether clones ofDaphnia pulexin a mesotrophic lake differ with respect to overwintering strategies:either surviving the winter as parthenogenetic females with reduced metabolism in pelagic ...
Assessing ecological responses to catastrophic amphibian declines: Patterns of macroinvertebrate production and food web structure in upland Panamanian streams
Assessing ecological responses catastrophic amphibian declines
2014/4/17
As part of the Tropical Amphibian Declines in Streams (TADS) project, we estimated macroinvertebrate
production and constructed quantitative food webs for four headwater stream reaches in the Panaman...
Diel vertical migration of the deep-water jellyfish Periphylla periphylla simulated as individual responses to absolute light intensity
he deep-water jellyfish Periphylla periphylla simulated absolute light intensity
2014/4/17
We evaluate the hypothesis that the vertical migration of Periphylla periphylla is governed by its sensitivity to
light intensity. By applying an individual-based model where random walk is combined ...
Frequency responses of immersing tunnel element under wave actions
immersed tunnel motion response frequency domain linear potential theory
2011/9/9
The immersion of large-scale tunnel elements is one of the most important working procedures in the construction of an underwater immersed tunnel. To investigate the dynamic characteristics of tunnel ...
