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...
They say that, as you get older, your ability to absorb new information diminishes and your capacity to hold old information dwindles. Looking back over past issues of Oceanography, I realized that de...
Uncertainty Management in Coupled Physical-Biological Lower Trophic Level Ocean Ecosystem Models
Lower trophic level Marine ecosystem model Marine geochemistry the earth's climate system
2015/7/16
Lower trophic level (LTL) ocean ecosystem models are important tools for understanding ocean biogeochemical variability and its role in Earth's climate system. These models are often replete with para...
Synthesis of Pacific Ocean Climate and Ecosystem Dynamics
The Pacific Ocean ecosystem climate research climate control Pacific Ocean ecosystem
2015/7/16
The goal of the Pacific Ocean Boundary Ecosystem and Climate Study (POBEX) was to diagnose the large-scale climate controls on regional transport dynamics and lower trophic marine ecosystem variabilit...
Advances in Physical, Biological, and Coupled Ocean Models During the US GLOBEC Program
Global ocean ecosystem dynamics the climate system evolution ecosystem ocean modeling capabilities
2015/7/16
From the planning days preceding the establishment of the US Global Ocean Ecosystem Dynamics (GLOBEC) program, modeling was recognized as one of the program's pillars. In particular, predictions of fu...
Bioactive trace Metal distributions and Biogeochemical controls in the Southern ocean
Metal distributions Biogeochemical controls
2015/7/15
Extensive sampling in many regions of the Southern Ocean has
demonstrated that surface water concentrations of dissolved Fe are low enough
to limit phytoplankton growth. In contrast, there is curr...
Various human activities, including
fossil fuel combustion and forest clearing, emit
about eight petagrams (or billion tons) of carbon
in the form of CO2 into the atmosphere annually.
The glob...
Active Long-Lived Faults Emerging Along Slow-Spreading Mid-Ocean Ridges
Long-Lived Faults Emerging Slow-Spreading Mid-Ocean Ridges
2015/7/14
In the classic mid-ocean ridge model, new seafloor is generated through a combination of magmatic diking feeding lava flows at the spreading axis, and the formation of short-offset, high-angle normal ...
Recent Seismic Studies at the East Pacific Rise 8°20'–10°10'N and Endeavour Segment:Insights into Mid-Ocean Ridge Hydrothermal and Magmatic Processes
Seismic East Pacific Rise 8°20'–10°10'N Endeavour Segment:Mid-Ocean Ridge Hydrothermal Magmatic Processes
2015/7/14
As part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise (EPR) 8°20'...
Diffuse Flow On and Around Hydrothermal Vents at Mid-Ocean Ridges
Around Hydrothermal Vents Mid-Ocean Ridges
2015/7/14
Black smokers are the dramatic result of seawater being heated to high temperatures (generally 250° to 350°C) by magmatic systems, then discharging at the seafloor. However, not all seawater that circ...
The Oceanography Society (TOS) is proud to be the lead institution sponsoring the 2012 Ocean Sciences meeting February 20–24, 2012, in Salt Lake City, Utah. Meeting co-chairs Mel Briscoe (TOS), Eric I...
I will always remember my first visit to Scripps Institution of Oceanography to see Walter Munk. It was a November lunchtime when I arrived at a sun-drenched Institute of Geophysics and Planetary Phys...
Integrating Biogeochemistry and Ecology Into Ocean Data Assimilation Systems
Integrating Biogeochemistry Ecology Ocean Data Assimilation Systems
2015/7/6
Monitoring and predicting the biogeochemical state of the ocean and marine ecosystems is an important application of operational oceanography that needs to be expanded. The accurate depiction of the o...
Ocean data assimilation has matured to the point that observations are now routinely combined with model forecasts to produce a variety of ocean products. Approaches to ocean data assimilation vary wi...
Oceanographers today are more aware than ever of the importance of ocean science, particularly for understanding global issues such as climate change and the repercussions of fishing on ecosystems. No...
