What are PCBs? PCB stands for Polychlorinated Biphenyls, and represents a grouping of man-made chemicals that consist of carbon, hydrogen, and chlorine. PCBs were first produced in the late 1920’s / early 1930’s, and were continued to be used in products until its ban in 1979 (Toxic Substances Control Act) due to the toxicity of PCBs and its negative impacts on biological organisms. There are a range of PCBs, with varying consistencies (from a thin liquid to a thick wax) as well as varying degrees of toxicity. PCBs were very popularly used in a large variety of products due to their “non-flammability, chemical stability, high boiling point, and electrical insulating properties” (EPA). Some examples of products listed on the EPA’s website for things that previously contained PCBs include: · Pigments and dyes · Oil-based paint · Caulking · Plastics ·…

Underwater or ocean noise can have natural/biological sources or anthropogenic sources, otherwise known as human-made noise. Ocean noise is very important to monitor due to its impact on the environment and the organisms within. Natural sources of ocean noise have physical/geophysical, atmospheric, and geological aspects. These aspects can include wind and precipitation at the ocean…

Humpback whales have always been characterized by their large pectoral fins. In fact their scientific name, Megaptera novaeangliae, translates to “big winged New Englander,” paying homage to their nearly 15 foot fins. These fins are specifically designed to be extremely hydrodynamic, allowing for easy movement through the water, despite their size. They are so efficient, that…
