Andrew Lucas PI

A Turbulent Affair: The Epsilometer, the Wirewalker, and the Epsifish

Analyze data, write up processes / findings, build some of parts for epsilometer, help around lab where needed.

Basic knowledge of Matlab, understanding of basic physics relating to ocean dynamics (though what kind depends on your specific lab).

Physiology / Neuroscience

Dariusz Stramski PI

Investigation of Inherent Optical Properties of Seawater and Applications of Inverse Optical Models in the Arctic Ocean

My responsibilities included, but were not limited to, writing algorithms, validating algorithms, and applying algorithms to satellite data. My goal was to determine where these algorithms struggle and find out why they struggle. I really enjoyed the  independent experience I gained, as I would often find myself asking questions about why something doesn't work or why something happens, and then applying my knowledge and tools to discover answers to these questions.

Everything! From having strong communication skills to computer coding and everything in-between all skills I've learned through college coursework helped me succeed at SIO.

Physics

David Chadwell (PI)

Observing Marine Geophysics: GPS-Acoustic Measurements in the Cascadia Subduction Zone

My responsibilities included testing GPS equipment, assisting in research activities on cruises, small boat operations with the wave glider off of Scripps Pier, recording and editing GoPro footage, and data analysis of past years. 

I felt very confident in working with GPS data and surveying equipment because of my academic background. I also felt like I could critically think through problems to solve during my internship.

Geographic Information Science 

David Chadwell (PI)

Observing Marine Geophysics: GPS-Acoustic Measurements in the Cascadia Subduction Zone

Assisted research in measuring crustal deformation through seafloor mapping. Conducted testing to confirm repeatability and accuracy of instruments. Designed mission plan for unmanned ocean navigation vehicle.

My basic engineering and handywoman skills were helpful for testing equipment. Additionally, my data analysis skills in Excel and statistical knowledge were helpful. 

Environmental Engineering

Grant Deane PI

Using Bubble Noise to Measure the Melting Rate of Glacier Ice

I had my own project, trying to use bubble noise to measure the melting rate of glacier ice. My PI was very results-oriented, so I didn't have any day to day responsibilities, as long as I was productive.

I think nearly everything was learnable during the internship, as long as I was willing to put in the effort and not say "I don't have time to learn that." It was helpful that I knew a bit of Matlab and that I read up on bubble dynamics before coming. 

Physics

Hee-Chun Song PI

Snapping Shrimp Acoustics

Debugging a program and using it to process data involving snapping shrimp snaps.

Computer science.

Electrical Engineering and Physics

John Hildebrand PI / Natalie Posdaljian

Programming (especially data visualization) and practice giving presentations.

Geophysical Sciences

Matthew Alford PI / Andrew Lucas PI / Michael Goldin

A Turbulent Affair: The Epsilometer, the Wirewalker, and the Epsifish

I helped create probes for the epsilometer and helped design things for my supervisors, engineers, and scientists in the lab whenever they needed a part or device made. After I designed those objects, I would use the tools provided in the lab to create them.

My design and structural engineering classes helped me with my understanding of devices and mechanisms that I was introduced to at work. They also helped me with my understanding of design processes.

Structural Engineering

Wiliam Hodgkiss PI

Measuring Sensitivity of Parameters Using Matched Field Processing

I was given the task to do matched field processing on the SWellEx-96 experiment data and then from there investigate the sensitivity of the matched field results as a parameter was varied.

Develop and test the hardware and software to create a camera timelapse, then begin extending that project further towards the goal of creating a sensor-actuator relationship between a hydrophone array and a Sony camera.

My hardware/software knowledge was helpful but didn't completely align with what I was doing. Most of my engineering education did not help me at all except that I have a lot of experience problem solving.

Civil and Environmental Engineering

Ana Sirovic PI

Detecting Life: A Two-Stage Threshold Detector For Fish Calls in the Gulf of Mexico

Helped a graduate student with data collection for research project on fish in the Cayman Islands. Halfway through, transitioned to my own project of using a detector and convolutional neural network classifier to detect and classify fish calls in the Gulf of Mexico near the site of the BP oil spill.

Experience with MATLAB data processing was definitely beneficial to the work I did.

Investigating Geoacoustic Properties of Seabed Sediments Offshore Rhode Island

Responsible for effectively learning about digital signal processing and ocean acoustics from texts and lecture materials provided by my PI. I then applied those principles to plotting the spectral content of acoustic data, and modeling the acoustic waveguide based on measured qualities of the environment, especially seabed sediments.

My physics, physics lab, math and geophysics classes were helpful because I had some idea of the background and basis of my work coming in. Especially helpful was my note-taking habits that I developed in physics lab, so that I would have detailed records of everything I did each day, which made it easy to pick up where I left off.

Physics

Dariusz Stramski PI

Determinations of the Volume Scattering Function and Depolarization Ratio of Pure Seawater

Participation in laboratory experiments to measure multi-angle light scattering of pure seawater with DAWN instrument and determine the dependence of depolarization ratio of pure seawater on salinity of water.

Analyzing the State of Fault Locking on the Frontal Thrust of the Cascadia Subduction Zone

Monitoring wave glider power status, piloting website, learning to operate components of wave glider, understand the goal and methods of our project, launched WG off coast of Newport, Oregon, and retrieved it.

Some of my previous geologic knowledge helped me to understand the process of how tectonics move and what we're trying to accomplish from this research.

Geology

Eric Terrill PI / Megan Cimino / Sophia Merrifield

Phytoplankton Blooms and the Diurnal Warm Layer in Southern California

Used MATLAB to analyze data from the Langmuir cruise, specifically looking at wind and chlorophyll data.

investigating the Spectral Characteristics of Snapping Shrimp

Frequently met with a graduate student in my lab and did various processing of acoustic data. Worked primarily on looking at changes over time by testing individual time slots.

My ability to use MATLAB was very useful for my internship.

Applied Mathematical Sciences

Jules Jaffe PI

Micro Flow Over Fish Scales

Worked on developing and validating our experimental setup, coded, adapted, and tested analysis for experimental use, gathered data, and analyzed results. Basically a mini-slice of the scientific process.

Programming experience, background in math should include linear algebra and at least calculus for physics-oriented work

Applied Physics

Ken Melville PI / Luc Lenain

Finding Stokes' Drift of Deep Water Solitons

Was able to devise my own experiment (under significant guidance) and conduct tests in the wave tank of the Hydraulics Lab. Lab experiments were supplemented by lots of reading and signal processing.

I found the knowledge from my Mathematical Physics and Circuits classes to be unexpectedly useful. This internship reinforced the idea that I should learn more math (which doesn't get reinforced that often in daily life).

Engineering Physics

Matthew Alford PI / Andrew Lucas PI

Time of Flight: Measuring Water Current Velocity With Ultrasonic Transducers

Responsible for testing and calibrating time to digital converters and ultrasonic transducers which would be used to make a water velocity sensor. In addition to working with the electronics, was also responsible for CADing and machining test equipment and for helping out with general lab tasks.

My engineering background was a huge help during my internship, but my past experiences on extracurricular project teams were just as helpful, if not more helpful, than my classes. As a part of my project teams, I gained the skills and hands-on experiences that really helped me to thrive in an actual engineering environment. In particular, having prior programming, CADing, and soldering experience helped immensely, though I'm sure I would have been fine without these skills too. Everyone in the lab was more than willing to teach me the skills that I needed.

Electrical Engineering

Matthew Alford PI / Gunnar Voet PI

Abyssal Transport Through the Samoan Passage

My job was to take data given to us by JPL/NASA that came from the MIT general circulation model and analyze it using MATLAB. I would extract different sections of the data for an area in the Samoan Passage, do various calculations such as velocity sections and volume transports. I would also make plots to visualize the data.

Organismal Biology

Simone Baumann- Pickering PI / Ana Sirovic PI

Spacial and Temporal Patterns of Cetacean Sounds in the Antarctic

Mostly logged data (different types of whale sounds) using Triton and MATLAB, pretty reasonable responsibilities because I am a biology major, rather than physics or engineering.

I am a biology major which was very useful in the bioacoustics lab because I had a solid foundation in ecology which is one of their main focuses. It helped me when analyzing my data for my presentation.

Biological Sciences, B.S.
