There's much more to come.
I'm posting to social media quick vids and photos along the way.

|Hannah and Kit work together to collect the water sample|
and poison the sample to stop the biological processes.

Meet the team:Rachel Vander Giessen, 33, has had a passion for the ocean as long as she's lived in Seattle. All of her life. After graduating from high school, her passion propelled her to apply for the Maritime Marine Academy in Seattle, like so many of the full-time crew on board the Melville, but a subpar math score on the entrance exam kept her from pursuing this dream. Ironically, her degree now is in physics. "All it took was a good professor," she explained, to change her mind and turn her on to the mathematical world around us. After a few years of crewing private vessels through the inside passage to Alaska, she finished her degree and began volunteering at UW. It was on another research cruise as a volunteer with Jan Newton (UW) to repair the Cha Ba buoy (one of our sites of interest) that she was offered a permanent job with the university that has led to her work here with us.
|Rachel holds the clipboard and lets each person know when|
to start sampling. This helps avoid confusion and contamination.

|"Kit" Kallista Angeloff|
|Kit stops the biological processes, |
preserving the chemistry of the sample.
|Tweeted this ad because "Chuck and the Rad-Van" sounded like a band |
that could be playing in our destination: Seattle!

the very next day that same volcano erupted!It's a pretty amazing story. But, it didn't make the impact that the pictures do.

This group has been incredible, and it stems from the leadership.

London, Ontario, will be spending 12 weeks after
our research at sea in Bermuda with BIOS, Bermuda
Institute of Ocean Sciences as an intern with more time at
sea on the R/V Atlantis.

|These are the samples before the diluted hydrochloric|
acid (HCl) is added to each.
|Brian uses this special pipette to add 0.1mL to each sample.|
|After the HCl (diluted hydrochloric acid) is added,|
the samples change colors (indication of chemical change).
The lighter blue or clearer indicates high amounts of
domoic acid. This one is off the charts.
|The plate goes into machine that reads the optical density of each sample.|
