These past couple weeks at sea have been an incredible experience and I am excited to share what I have learned with the Peddie community. Being aboard the “America’s Ship for Ocean Exploration” and mapping a region of the seafloor that has not been studied yet was a very exciting opportunity as both a scientist and educator. I plan on creating and teaching a Marine Science elective during the Spring of 2019.  Data collected from the expedition will be utilized to design classroom activities, laboratory experiments, and cross-curricular materials that directly relate to the research completed. Students will understand the importance of exploration and be encouraged to discover, inform, and educate others about the ocean. Since the Okeanos is equipped with telepresence capabilities, I will be able to stream seafloor images, ROV dives, and interviews from sea in my classroom. Having students directly engaged with those completing research in real time will enable them to make associations between the ocean and their local ecosystems to put the research into context.

I really enjoyed meeting everyone aboard and listening to their stories. Since these vessels require 24/7 operations, many people worked very hard over the course of the expedition to ensure that everything was going as planned. The crew, stewards, engineers, NOAA Officers, scientists, and explorers in training were very willing to share their knowledge, insights, and experiences.  I respect their dedication and flexibility while at sea and I am very grateful to have met such awesome people! This experience was definitely one of the highlights of my teaching career and I am very inspired to know that no matter where in the world the Okeanos is located, everyone aboard is committed to understanding the wonders of the unknown ocean.

Air Temperature: 27.5°C

Wind Speed:  18.17 knots

Conditions: Partly Sunny  

Depth: 3742.65 meters

Qimera is a hydrographic processing software that was used during this expedition. This computer program allows scientists to edit and process the survey line data as it was being collected. 

Qimera Survey Area
The survey area 200 nautical miles off the coast of Bermuda projected in Qimera. Warmer colors indicate depths close to 4,000 meters while the cooler colors represent deeper regions up to 5,500 meters.

To successfully edit incoming multibeam data, it was necessary to isolate a specific section of the line and use Qimera’s 3D Editing Tool. The 3D Editing Tool was utilized to remove outliers that skew the data.

Essentially, each colorful point in the diagram below is a sounding from the multibeam sonar. The soundings are return signals that bounce back and reach the receivers on the sonar. When scientists are previewing and editing data, certain points are considered outliers and are rejected. The rejected points are shown as red diamonds in the diagram below. Once the edits are made, they are saved, and the surface is updated.

It is especially important to ensure that we are collecting as much data as possible as we continue to survey this area. In order to accomplish this, factors such as required resolution, sea state, water depth and bottom type are used to determine line plans.  By partially overlapping lines, we ensure there is quality data coverage on the outside beams. More overlap tends to mean denser, high quality coverage which will allow our team to develop accurate maps of the seafloor.

Another program that was used to process data was known as Fledermaus. This interactive 4D geospatial processing and analysis tool is used to reproject Qimera projects as well as export the Daily Product that was completed and sent onshore where it is publicly available. We also projected the edited data on Google Earth (see below) and would include this in the Daily Product that was sent to shore as well.

Now that we have left the survey area, we are transiting back to Norfolk and still collecting and processing data. We are scheduled to arrive early on the 31st and a majority of us will depart that evening. Since we are still collecting return transit data, it is still necessary for processing to occur. Although we’ve been working diligently, we still like to make time for fun. On Friday night, we hosted a Finer Things Club Gathering complete with fancy cheese, crackers, sparkling apple juice, and chocolate! It was great! On Saturday, we played the final cribbage tournament game as well as other board games, and on Sunday we had an ice cream party!

Science and Technology Log

Since the Okeanos Explorer is known as “America’s Ship for Ocean Exploration,” it is equipped with two important vehicles that allow scientists to study normally inaccessible ocean depths. Deep Discoverer (D2) is a remotely operated vehicle (ROV) that is mechanically designed with software and video engineering programs that generate precise images and videos. A total of nine cameras, including a Zeus Plus camera with impressive zoom capabilities, produce high-definition images that give scientists and those on shore insights about deep-sea ecosystems. The 9,000 pound ROV contains approximately 2,400 feet of intricate wiring as well as specially designed Kraft predator hand that can hold up to 200 pounds. The hand is especially useful for deep-sea sampling and allows scientists to bring certain organisms to the surface for further analysis. D2 can dive up to 30 meters per minute and is designed to withstand pressures almost 600 times that at sea level.

D2 does not operate alone during the eight-hour dives. Instead, it relies on assistance from Seirios, another 4,000-pound machine known as a camera sled. This device is powered and controlled by the Okeanos Explorer and offers the pilots and scientists a wide-angle perspective as they navigate the ocean floor. Seirios is tethered to the Okeanos Explorer and illuminates D2 from above to allow for increased visibility. The frame of this machine is relatively open which increases the distance cameras can be separated from the mounted lighting. This design reduces the light that reflects off particles in the water (optical backscatter) and results in high-quality images.

All of the deep ocean images and video collected by D2, Seirios, and the Okeanos, can be transmitted to the rest of the world by satellite. The Okeanos is fitted with telepresence technology that enables everyone involved in the operation to provide scientific context to the public. The ability to broadcast this exciting information requires effective collaboration between the Engineering Team, NOAA ship crew, and scientists both onboard and onshore. It is amazing that anyone with Internet connection can be involved the expedition and science in real time.

Personal Log

In order to make it back to Norfolk on time for dry dock, we will have to finish our mapping our survey area on the 27th. In the meantime, we have been continuing to process data, collect sunphotometer readings, launch XBTs, and play cribbage. Our cribbage tournament will conclude on Friday night! Everyone aboard is excited about the data we’ve collected and looking forward to a successful end of the expedition.

Sid Dunn

Hometown: Virginia Beach, Virginia

Although you would never guess it, Sid is the newest member of the Okeanos Explorer and has been working on the vessel since June 7th. He recently retired after sixteen years as an insurance agent specializing in business claim adjustments. Since his wife’s family is involved in the maritime industry, he thought it would be interesting to research potential post-retirement careers in this field.

Sid began a 5-week training program at the Mid-Atlantic Maritime Academy. This institution is a highly respected, state-of-the-art maritime training center established for individuals who seek to enter a maritime profession. After his training period, Sid completed a two-month internship on the tall ship Oliver Hazard Perry in Rhode Island. Sid sailed from Newport, Rhode Island down to Galveston, Texas while on the Oliver Hazard Perry.

Once he completed his training and internship, Sid was hired as part of the permanent crew aboard the Okeanos Explorer. Sid is a General Vessel Assistant (GVA) and performs work in the deck and engine departments. He is responsible for standing watch two times per day. These watches are four hour time periods and aboard this cruise, he is scheduled from 0800-1200 and 2000-2400. During his watches, Sid performs rounds throughout the entire ship to ensure the safety of the vessel, completes routine maintenance, and stands watch on the bridge. Sid really enjoys being out to sea and is excited to continue his new adventure on the Okeanos Explorer.

LT Rosemary Abbitt

Growing up in Norfolk, Virginia, Rosemary spent much of her childhood around the ocean. She was fascinated by the sea and had a strong desire to learn as much as she could about marine ecosystems. During her high school career, Rosemary participated in a summer travel program at the Forfar Field Station in the Bahamas on Andros Island. This experiential learning opportunity allowed Rosemary to be directly involved with field-studies that focused on scuba diving and exploration. Thanks to that unique experience, Rosemary was hooked on marine science.

After Rosemary graduated high school, she earned her Associates Degree in General Studies of Science at a local community college, then transferred to Coastal Carolina University (CCU) to continue studying marine science. During her undergraduate career, she completed an independent research project in Discovery Bay, Jamaica and focused her studies on coral ecology. After she earned her degree at CCU, Rosemary was interested in becoming a NOAA Corps Officer. Since a few of Rosemary’s family members worked for NOAA, she was exposed to the Corps mission and impact from an early age. She applied and did not gain admittance; however, that did not set Rosemary back.

Rosemary started working as a Physical Scientist intern at the Atlantic Hydrographic Branch in Norfolk, Virginia and sailed aboard NOAA Ship Thomas Jefferson for two field seasons. After this experience, she reapplied to the Corps, was accepted, and began her Basic Officer Training Class at Kings Point Merchant Marine Academy in February 2012. Officer training school was an intense program that emphasized leadership, teamwork, seamanship, and navigation. Once Rosemary graduated, her first sea assignment was on the hydrographic research vessel, NOAA Ship Rainier in Alaska. After this assignment, Rosemary’s land assignment was at the Florida Marine Sanctuary in Key West. She worked as a support diver to assess coral health and completed grounding assessments for three and half years before rotating to her current position as the Operations Officer aboard Okeanos Explorer. Now, Rosemary is involved with deep sea exploration and loves being on a ship that is dedicated to discovering more about the unknown parts of the ocean. Rosemary is enthusiastic about supporting NOAA’s mission of science, service, and stewardship. She believes that it is incredibly important to set goals, remain determined, and push yourself out of your comfort zone to experience success.
