This is a just a shallow <~100m on the shelf to obtain sediments. This site is of particular interest to the team surveying with genomics to find Hodarchaeales, which are a member of the Asgard archaea that are closest to eukaryotes on the tree of life. We expect the seafloor to be flat. Once a suitable site is found we will fire the 6 niskons, and those we are just planning on collecting a full set of 18 push cores, after the 6 niskons are fired. We don’t not expect to see rocks or biomats, but if we do we’ll collect some, ok if this is not done.

This is the first slope sampling station on this expedition. We have no idea what we are going to see or find for sediment samples. As a result, we are going to explore the area quite a bit. We plan to get cores from 2 waypoints (9 cores at each); however, this can change depending what we see. We will land near deploy point then head NW upslope to explore. I expect coring to be a bit more challenging here, so it will take a bit to find a good place to get sediment samples. Ultimately, we expect this site to contain novel branches on the tree of life, that we will identify by doing genomic sequencing.

We are moving further down the slope to search for different sediment types than the previous station. We hope to start at the base of a canyon, then explore and find a coring site. We will then move up the wall to the top and collect more cores.

We are sampling off the coast of Uruguay, on the continental shelf in the Atlantic Ocean, near La Poloma. This location is close to shore in the paleochannel. The objective of this dive is to collected marine sediments on the continental shelf of South America to understand the ecology and evolution of Asgard Archaea. These are a group of microbes that are closest to eukaryotes (including plants and animals) on the tree of life. We will be diving in a shallow site just ~65m from the ocean surface. We are going to be using this mud to obtain genomes, culture, and do physiological experiments on the Asgard Archaea.

These are a group of microbes that are closest to eukaryotes (including plants and animals) on the tree of life. We will be diving to a site that is roughly 2,300m from the ocean surface. We are going to be using this mud to obtain genomes, culture, and do physiologica experiments on the Asgard Archaea. Since nobody has used the genomic approaches, we are in this part of the ocean, we have little understanding of the microbial diversity present here. So, we are surveying the biodiversity by looking at proteins that can be used to place them on the tree of life. As a first pass here at sea we are targeting lineages that are unique from what has been seen before. So, by “novel and high interest” we are looking completely new phyla (anywhere on the tree) and new lineages of Asgards.
