2017 AAUS/OWUSS Internship — Final Week in California

As the weekend quickly came to an end, the second week of class began. I was rested and ready to go! The second week of the course really dives into the training of different types of scientific procedures and processes that assist scientists in the field. Buddy teams are changed every day in order to help you not become accustomed to the same diver each time. With scientific diving, you may have multiple different buddies and it is helpful to learn how to approach this in training. In order to get all of the buddy teams on the same page, a short dive briefing was given by our instructor to explain the goal of each dive.

In addition, another safety measure before beginning your dive was a check in on the surface with your dive plan (planned time, depth, psi in, psi out, dive table letter group, etc.).

I really looked forward to Monday because it would be my first time diving in a kelp forest. Originating from New England and never traveling to the West Coast prior to this course, I had heard about kelp forests. However, now was my chance to finally have a firsthand experience! This would also be our first day diving off small boats. At SIO, the process for using boats is a little different than most places. The system is used to minimize the time it takes to launch a boat. The boat ramp would add an hour to the procedure since it is located at Mission Bay Park, San Diego, California. The boats are launched off the pier, using a crane system to pick the boats up, bring them over the side of the pier, and then lowered into the water. Then each person has to climb down a 30 foot chain ladder to get on to the boat!

Tuesday broke the normal routine of dives in the morning and classroom in the afternoon. We had a deep dive and beach entry in the morning from La Jolla Shores and a night dive was planned for the evening. The deep dive was done in groups of four students and one dive instructor. We surface swam out to the canyon from La Jolla Shores and then descended and explored. While heading back, each member of the group had enough air left for us to swim underwater until we hit about 5 feet of water and were basically back at shore. The night dive was back off SIO pier. We were tasked with more search pattern practice for this dive, which became a lot more difficult at night!

Wednesday we were back at SIO Pier to put our search and recovery skills into action. On the first dive, we were to search and recover two chains (approx. 10 pounds) that were thrown off the pier. The catch was that we did not see them thrown, but another buddy team would have to explain to us their approximate location. On the second dive, we were to find a “spider” which is a large metal object that is used to hold various underwater data collection machines. The “spider” was weighted down with ~50 pounds, so we also had to put our lift bag skills into action.

We then got to tour behind the scenes of Birch Aquarium, which is the aquarium at Scripps. Melissa Torres, who gave us the tour, is in charge of diving operations at Birch Aquarium and also an instructor for the course. We got to see the tanks that can be dove in, both behind the scenes and from the general public’s perspective.

Thursday concluded the scuba diving portion of the course. We were back on the small boats and dove Mia’s reef, which is an artificial reef. Small boat diving utilizes the seated back roll entry. This course was the first time I used this skill, and it is a lot easier than I had originally thought! In addition, we were also diving NITROX after learning the classroom material. I had never dove NITROX previously, but there are many benefits to this certification, such as extending bottom time at deeper depths. The first dive we completed a transect, collecting counts and sizes of different kelp species. The final dive of the class was reserved for a fun dive! We got to explore the reef, but always keeping in mind good diving practices and the skills we learned throughout the course!

Often the conditions were not optimal during the course, but this forced us to perfect our skills with even more accuracy. For example, we had to deal with surge while trying to take measurements and maintaining neutral buoyancy. Conditions are one factor that you need to take into consideration while planning scientific dives. You need to be realistic about whether or not you can complete the task within the given conditions that day. If it is not feasible, you should reschedule when the conditions are more optimal for your plan.

On Friday, the final day of the class, we took the final exam. This was a cumulative exam that covered all of the material from the course. This course is not only about scientific scuba diving skills, as much as it is about physically and mentally preparing yourself to complete the tasks at hand, even if you are exhausted. In addition, it is about adjusting to the conditions. California water is a brisk ~55°F and 5-25 foot visibility, something I had not dove very often.

Even with all these new skills to learn, there is always time to have a little fun!

After 19 days in California and three different hosts who graciously let me stay at their homes, I am headed back home to Massachusetts for a couple weeks. My next adventure will begin at the end of July when I head to Savannah, Georgia to work with NOAA at Gray’s Reef National Marine Sanctuary. I am really excited to see what this opportunity presents and am ready to get started!

Hello, my name is Erika Sawicki and this year I received the OWUSS-AAUS Dr. Lee H. Somers Scientific Diving Internship. I am from a small town called Wilbraham, Massachusetts and recently graduated from the University of New England in Biddeford, Maine with a double major in Ocean Studies & Marine Affairs and Environmental Science and a minor in Philosophy. I am extremely grateful for the Our World-Underwater Scholarship Society (OWUSS) and the American Academy of Underwater Sciences (AAUS) for their continued effort to create a positive and meaningful learning experience for me this summer.

After an interesting turn in events, I found out I would be completing my AAUS Scientific Diver Certification in La Jolla, California at the Scripps Institution of Oceanography (SIO) with Diving Safety Officer (DSO) Christian McDonald. One week later, I was on a plane across the country to Los Angeles… Next, I was greeted with the wonderful California traffic and a four hour drive to San Diego.

My first night in San Diego I was warmly welcomed by Faith Ortins and Jeff from Diving Unlimited International (DUI). I had the opportunity to take a tour of DUI and learn how a drysuit was made. It was really fascinating to learn that almost the entire process is done by hand.

For the rest of my time in California, I was warmly welcomed to stay at Mary and Sally’s condo. Sally Wahrmann is a member of the Women Diver’s Hall of Fame (WDHOF), with extensive knowledge and dive experience of the NE wreck Andrea Doria. After a couple of days of settling in and exploring the area, my Scientific Diver course began on Saturday (6/17). It is a two-week intensive course consisting of very long days, starting at 7:30 am and ending around 5:30/6 pm each day. In addition to our class, homework was required each evening.

Prior to enrolling in a Scientific Diver course you have to fulfill the pre-requisites, which include a medical exam, first aid and emergency oxygen certification, and a recreational SCUBA certification. The AAUS Scientific Diver course includes a minimum of 100 hours of training and 12 dives, along with a swim test, confined water checkouts, and open water checkouts. In addition to the Scientific Diver certification, at SIO you are able to receive Advanced Open Water, Rescue Diver, Oxygen Provider, and NITROX certifications during the course. I had previously received all but the NITROX certification, but it was a great opportunity to review this material. The class had a wide range of experience levels, but everybody worked together well.

Saturday was an introductory day filled with the swim test and snorkel skills in the pool, along with a swim out to the pier (1,090 feet) and free dive down to the bottom. On Sunday, we started to use our SCUBA equipment. The importance of buddy checks was stressed; no matter how much other planning is happening at the surface for your scientific procedures, a buddy check should always be included. Buoyancy is also an important skill that we practiced. As well, we practiced different scuba entries into the pool, such as the back roll (for small boats) and giant stride.

Monday started in the pool with different stress tests, such as getting gear from the bottom of the pool. We also practiced rescues skills. In addition, we determined proper weighting with our exposure suits and beach entries. Proper weighting will help with your buoyancy control. On Monday, we also started classroom lectures. For the rest of the course, we had a classroom session every day, usually after our dives. Tuesday we practiced our rescue skills in the ocean, which made the whole process a lot more difficult. This was also our first dive of the course. It was used to practice basic skills and explore our main dive site (SIO pier) for the course. Wednesday was our final pool session; we got to practice different skills, such as lift bags, transect measurements, assembly of equipment blindfolded, etc. Although challenging, it was a lot of fun to experience all of these new challenges.

      A black piece of plastic was placed in our masks to make it impossible to see when completing the tasks.

Thursday started our new schedule of two morning dives, followed by a classroom session in the afternoon. Each day had a different focus for the dives. For example, Thursday we focused on rescue skills and rocky entries, while on Friday navigation and search patterns were practiced. During our class session, we practiced providing oxygen. We learned how to set up the oxygen kits and also got to experience what it is like to receive oxygen. Oxygen is a life-saving tool that is necessary to be on site for all scientific dives.

After a long and exciting seven days, the first half of the class came to an end. I was exhausted and really looking forward to some sleep over the weekend before the second week began!
