New Sensor Technology for In Situ Measurements of Ocean Chemistry
New Sensor Technology Situ Measurements Ocean Chemistry
2015/8/14
Chemical processes in the ocean and at its interfaces with the atmosphere and the seafloor play a major role in regulating global biogeochemical cycles. Predicting the impact of human disturbances on ...
Knowledge of wave and surf conditions can play a major role in planning and executing a successful amphibious assault on a targeted beach (Figure 1). The dynamic surf zone is affected by waves that ma...
Introduction to Ocean Remote Sensing by Seelye Martin is an excellent textbook for teaching remote sensing of the oceans at the beginning of the 21st century. Since 1987, Dr. Martin has taught remote ...
What Corals are Dying to Tell Us About CO2 and Ocean Acidification
Ocean Acidification CO2
2015/7/22
Emissions of carbon dioxide are causing the oceans to become more acidic. Recent experiments show that this ocean acidification threatens many ocean ecosystems. The ancient past may provide a cautiona...
Changing Ocean Chemistry:An Introduction to This Special Issue
Changing Ocean Chemistry Special Issue
2015/7/17
The modern industrialized and urbanized world, dubbed the "Anthropocene" by Paul Crutzen (2006), includes the past 250 years of multiple human impacts. Nobel Prize winner and atmospheric chemist Crutz...
GEOTRACES is an international study of the marine biogeochemical cycles of trace elements and their isotopes (TEIs), designed by marine geochemists to accelerate TEI research under a global program. C...
The toxic metal mercury is present only at trace levels in the ocean, but it accumulates in fish at concentrations high enough to pose a threat to human and environmental health. Human activity has dr...
In 1896, Arrhenius provided the first roughly quantitative sense of the plausible magnitude of human-induced changes in the concentration of CO2 in the atmosphere. Since then, all chemists could be aw...
Deep Ocean Carbonate Chemistry and Glacial-Interglacial Atmospheric CO2 Changes
Deep Ocean Carbonate Chemistry Glacial-Interglacial Atmospheric CO2
2015/7/17
Changes in deep ocean carbonate chemistry have profound implications for glacial-interglacial atmospheric CO2 changes. Here, we review deep ocean carbonate ion concentration ([CO32–]) changes based on...
A Time-Series View of Changing Ocean Chemistry Due to Ocean Uptake of Anthropogenic CO2 and Ocean Acidification
Time-Series View Changing Ocean Chemistry Due Ocean Uptake Anthropogenic CO2 Ocean Acidification
2015/7/17
Sustained observations provide critically needed data and understanding not only about ocean warming and water cycle reorganization (e.g., salinity changes), ocean eutrophication, and ocean deoxygenat...
Persistent Organic Pollutants (POPs),Polycyclic Aromatic Hydrocarbons (PAHs),and Plastics:Examples of the Status, Trend,and Cycling of Organic Chemicals of Environmental Concern in the Ocean
Persistent Organic Pollutants (POPs) Polycyclic Aromatic Hydrocarbons (PAHs) Plastics:Examples of the Status Trend Cycling Organic Chemicals Environmental Concern in the Ocean
2015/7/17
Four decades of research have provided a reasonable understanding of the outline of the biogeochemical cycles of persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in coa...
Ocean Acidification:The Role of CO2.
The Moorea Coral Reef Long Term Ecological Research program affords a unique opportunity to study the implications of ocean acidification (OA) for coral reefs, as ongoing ecological and physical monit...
Diversity of Hydrothermal Systems on Slow Spreading Ocean Ridges
Slow Spreading Ocean Ridges Hydrothermal Systems
2015/7/16
The global mid-ocean ridge system spreads over a spectrum of rates, and oceanic crust formed at slow and ultra-slow spreading ridges (< 40 mm yr–1) differs from the more "ideal" layered structure form...
Could we, should we, knowingly pollute
the world ocean? It’s easy to think that
the ocean is awfully big, and maybe no
one will notice. Unfortunately, it’s too
late to debate this ethical issu...
