Chemistry of the Great Big Blue: Sedimentation

Chemistry of the Great Big Blue, marine science, Science, toxicologySeptember 21, 2010

Rocks erode, travel down rivers and eventually in the form of small particles, settle in river deltas and estuaries. Even smaller pieces can be carried hundreds of miles into the ocean. It’s all part of the natural process of sedimentation, but like many other natural cycles, this one has been hijacked by human activities. Development, […]

Chemistry of the Great Big Blue: Nutrients

Chemistry of the Great Big Blue, marine science, Natural Science, Ocean of Pseudoscience Week, Science, toxicologySeptember 7, 2010

The Great Big Blue looks like it contains nothing but water and maybe a little salt, especially out in the open ocean. However, this kind of sparse environment is exactly where the chemistry matters the most – it’s a fine line between not enough, too much, and just right. Given this, there’s no distinct myth […]

Chemistry of the Great Big Blue: Metals

Chemistry of the Great Big Blue, marine science, Natural Science, Science, toxicologyAugust 31, 2010

The ocean is full of metals and minerals that naturally occur such as zinc, copper, and cobalt and many marine organisms therefore depend upon access to those metals in small concentrations. However, inshore marine systems receive inputs from industrial, mining, and stormwater runoff that far exceed what these organisms can use. So what’s the effect?  […]

Chemistry of the Great Big Blue: Petroleum Byproducts

Chemistry of the Great Big Blue, marine science, Natural Science, Science, toxicologyAugust 24, 2010

In light of the BP oil spill, this week’s installment of Chemistry of the Great Big Blue will be particularly relevant to current events and hopefully already on the minds of everyone reading. Where do petrochemicals in the marine environment come from other than oil spills? Road runoff, refineries, plastic production, plastic degradation, atmospheric deposition […]

Tyrone Hayes, Atrazine, Syngenta, and a little DMX
