Uniformitarianism or Catastrophism vs. Plate tectonics

By Patricia Zapien and Jonathan Franco

Theories, Dates, People.



Uniformitarianism: 1830. assumption that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past and apply everywhere in the universe

- the work of geologist James Hutton, which was refined by John Playfair and popularised by Charles Lyell's Principles of Geology 


Catastrophism: (19th century) the theory that the Earth has been affected in the past by sudden, short-lived, violent events, worldwide

-geologist Charles Lyell built upon James Hutton's ideas 

The theory of uniformitarianism is more closely related to the theory of plate tectonics

R/V Melville day 19

Day 19- Interview
Ruth Musgrave (Chief Scientist)

Ruth Musgrave is PHD student at the University of California San Diego (UCSD) focusing on oceanographic fluid dynamics. Ruth was born in the west London, United Kingdom. From a young age Ruth was intrigued by math and the constant challenge that came with it. Moving to Australia at the age of 20 Ruth obtained a Bachelors in Science (BS) in physics from Melbourne University, followed by an honors in applied math from Monash University (Australia). Ruth worked as a Patent attorney for a year and dreaded every second of it. She moved to the United States to pursue a PHD which she is currently working on, and loves everything about it. "In most jobs you do the same thing every day, you're told what to do by your boss and do the same thing every day. My job is nothing like that and thats why I love it," -Ruth Musgrave. 

Ruth's favorite places to travel are;
East Anglia, United Kingdom - To visit family 
and Baja California, Mexico - because its wild, remote, you can get away and enjoy life.  

"The ocean is full of the most incredible currents, It blows me away." -Ruth Musgrave

Day 18- Interview 

Amy Waterhouse (Chief Scientist)


Amy Waterhouse is a post doc Physical Oceanographer. She is a Canadian native who currently resides in La Jolla, California. Amy grew up sailing, windsurfing, kayaking and swimming with her family as a  child and from a young age fell in love with the ocean. Following her heart she pursued her dreams and obtained a masters in oceanography at the University of British Columbia (UBC). After extensive field work and many expeditions in Florida, Mexico, and even Korea, Amy got her PHD at the University of Florida. She now works at the Scripps Institution of Oceanography (UCSD) as a post doc under the guidance of Jen MacKinnon.
Amy's favorite places to travel are Nuku Hiva in the Marquesas, and Papua New Guinea because they are beautiful, and the remoteness is just amazing.

R/V Melville shirt design day 17

I was asked to think of ideas for a group shirt design, i picked up a pencil and voila!  
And YES everything is hand drawn and I drew everything myself

R/V Melville day 16

Day 16 CUP DAY!!!

Today we sent around 100 cups 1335 meters so about 4380 feet down below the surface of the ocean. We attached a mesh bag filled with the cups above the CDT using a book clamp and after their descent  we recovered them and the results were AWESOME!!!

*Mr. Blas 3rd period class i will show you mine but you will all have to wait to see yours in class when I get back to land*  



My Cup (and yes i drew everything myself)

Super sunny day

Day 15: Question of the day

 Is Collecting data hard? -Patricia Patticakeslicious Zapien

What kind of stuff are you doing on the boat , on the second week ? -Carlos Reyes


-Collecting data is not hard, the instruments do all the work, however analyzing and writing code to compute the data is a challenge.
- During the second weeks we are doing CTD cast throughout Eel canyon gathering data on internal wave prorogation.

R/V Melville day 14

Day 14 Question of the day:

Do You Guys Have a Schedule like at School on the Ship ? -Kevon Mitchell

What kind of data does the mooring lines record? -Jerome Silvels 


-Onboard we schedule ourselves according to our watches or shifts, I personally wake from anywhere around 1-3 pm, sometimes get a bite to eat, or i will wait till dinner, after dinner have some free time then we have a science moment where somebody will speak and give a presentation on their field. soon after my shift starts from 8pm - 4am, and then begins the night shifts ritual of going for a soak in the hot tub on board while relaxing unwinding and gazing at the thousands of stars, then a quick shower and off to bed. So no we do not have a schedule like we do at school we have one a million times better!
-Mooring lines collect data on temperature, conductivity, depth, salinity, density, all to measure currents and obtain data on internal waves and hydraulic mixing.
