What is it about?

Analysis and identification of sources of photosynthetic pigments contained in sediments exposed to extreme environmental conditions in a deep hydrothermal system in the Guaymas Basin, Gulf of California.

Why is it important?

We report for the first time the accumulation of organic molecules in the form of photosynthetic pigments like chlorophyll-a and its derivatives contained en surficial sediments near active hydrothermal vent sites. It was demonstrated that some of the identified pigments have a bacterial origin.


Our contribution fills the gap in the search for possible organic carbon sources supporting the complex trophic web of deep hydrothermal systems which are mainly sustained by chemosynthetic processes.
