Finding best way to a whale’s diet through its skin
Skin, not blubber is the most effective way of revealing migrating whales’ diet, according to new Griffith University research.
Assessing the whales’ blubber and skin tissues, the Southern Ocean Persistent Organic Pollutants Program team from the Centre for Planetary Health and Food Security together with collaborators at the Australian Rivers Institute, concluded skin was the more suitable tissue for dietary assessment of humpback whales, but fats in the skin still interfered with the chemical signal.
“Blubber and skin samples taken with dart gun from whales migrating from Antarctica are often used to discover the make-up of their diet in the Southern Ocean, and how it’s changing over time,” said PhD candidate Jasmin Gross.

Elemental analysis offers scientists a method of determining the elements present in an organic compound, and in what quantity. Various fields of science rely on this type of analysis for research, quality control, and development. Medicine, engineering, and chemistry are just a few of the fields that utilize elemental analysis of organic compounds. Here, we discuss why it is important, and detail the most common method of elemental analysis of organic compounds, CHNSO analysis.
What is Elemental Analysis and Why Carry it Out for Organic Compounds?
Elemental analysis of a compound is the process by which a sample is analyzed to determine elements present and in what quantity. Sometimes, the sample’s isotopic composition is also defined. Elemental analysis can be categorized as being qualitative, where the presence of particular elements is determined, or quantitative,
