The Effects of Fish Processing Bio-waste on the Ocean’s Organisms and Nutrients
The effect fish processing bio-waste has on surrounding environments, habitats, and organisms is highly controversial. Although it is a natural pollutant, fish bio-waste has the ability to affect oxygen levels, salinity, temperature, pH levels, and the overall abundance of organisms in sea water.
Common Cations on DNA Degradation
The process of DNA degradation is important to many scientific studies. Heat treatment is the standard procedure used to degrade genetic material by heating DNA-containing media past the DNA melting temperature
The Effects of Declining Sea Ice on Narwhals
Narwhal populations number around 80,000 individuals (Laidre, n.d.). Threats to narwhals include polar bears, orca whales, and entrapments in sea ice (“The Narwhal’s Tale: Surviving Sea Ice Change,” 2012). Other potential problems include the melting of global sea ice, which will reshape their habitat.
The Effects of Tributyltin on the Marine Environment
Pollutants that resist breakdown and accumulate in the food chain are of great concern because they are consumed or absorbed by fish and other marine wildlife, which in turn are consumed by humans (NOAA, 2003). One of the most dangerous and controversial contaminants today is tributyltin (TBT). Tributyltin is one of the most poisonous substances to be released to the aquatic environment (Knutzen, 1995). It is used in many of the world’s marine paints to keep barnacles, seaweed, and other organisms from clinging to ships.
Garbage Patches Threaten Oceanic Life
A “plastic soup” of waste floating in the Pacific Ocean is growing at an alarming rate and now covers an area twice the size of the continental United States. In 1997, the oceanographer Charles Moore discovered this garbage patch. Ninety percent of these sea wastes are plastics. This study focuses on the impact of plastics to marine life and specifically to the albatross colony of Alaska.
