Science and Technology Log
Safety is first in the science classroom AND on board the NOAA Ship Nancy Foster too. Our expected departure was delayed by one day because the Public Announcement (PA) system was not working. Without the PA system, communication about emergency situations would not be possible. The ship’s crew worked to solve the problem themselves and also contacted outside help, but in the end a part had to be replaced so we stayed in port at Key West an extra day. Ships don’t sail without meeting safety requirements. By morning on Friday the system was working fine and the crew prepared to set sail.
After boarding the NOAA Ship Nancy Foster one of our first tasks was to review the safety protocols of the ship with one of the ship’s officers. We learned the whistle signals for man overboard (3 prolonged blasts of the alarm), fire (1 continuous blast of the alarm) and abandon ship (7 or more short blasts followed by 1 long blast) and the designated places to report in these situations. We will be practicing abandon ship in a drill very soon so I will report on that later. Since the ship works on a 24 hour schedule someone is always awake on board which means someone is always asleep too. Lt. Slater stressed the importance of not being too loud and showing respect for others’ space. After all this ship is home to the crew and the science team are guests in that home.
Teamwork is critical on board the ship. The science team and the ship’s crew work closely to help each other achieve the best results and stay safe. Most of the data collected on this cruise uses divers. Twice each day, the science team meets to review the Plan of the Day or POD. This meeting allows team members to learn the expectations of them to meet the research objectives of the day. They also have the chance to provide input or to ask questions. What do you think is a main focus of this meeting? You got it…Safety! While we waited for the PA system repair, the scientists checked their SCUBA gear again under the supervision of the ship’s crew members. This double-check insures all the equipment is safe to use.
After we steamed away from the keys, the scientists did a practice dive to simulate an unconscious diver at the surface. This drill included 5 science team divers as well as the ship’s crew and allowed them to practice their response in an emergency situation as well as deploying a small boat. A debriefing meeting afterward helped to identify the important tasks that need to be completed in the event of an emergency. Practicing through drills allows a quick response to an unusual situation and helps everyone stay safe.
With the safety issues well-covered, the science team is ready to begin retrieving the “listening stations” called VR2s from their positions on the ocean floor tomorrow. VR2 stands for Vemco Receiver 2 and is the model of the equipment used by the scientists use to collect fish movement information. What do you think the “listening stations” are listening for? Read about the “listening stations” in a future posting of my blog. For now you can make an educated guess by reading for hints in this blog and answering this poll.
Flying out of Reno, NV the plane took off heading south climbing quickly into the sky. From my window seat I could see Pine Middle School below. Then after a quick glimpse of Lake Tahoe to the west, the plane turned gracefully eastward. As I looked down I could see the desert valleys that once lay beneath the ancient Pleistocene lakes, covering a good part of the Great Basin with water. Although it doesn’t seem possible, one can still find shells and marine fossils in these now desert locations. I thought how different the landscape is today compared to the distant past. Our environment is undergoing constant changes even though the processes may seem slow and may not be noticed from day to day.
This is why it is important to observe, record and think about all aspects of our environment and to be aware of small changes so we can predict if they may become big impacts. Soon I would be landing in Florida, a state very different from Nevada, and joining the science team aboard the NOAA Ship Nancy Foster. This team is one of many that makes observations of their marine ecosystem, recording data and interpreting any changes or patterns they notice. I am very pleased to join them for the next 2 weeks and expect to learn a great deal.
Greeting me at the airport were artistic decorations made of models of tropical fish found along the Florida coast. High on the walls, they are creatively arranged in geometric patterns reminding me of synchronized swimmers competing in the Summer Olympics. These fish are more than art. They represent an important economic factor to Florida. They lure tourists for diving and snorkeling activities. Some of them are harvested for food or fished for sport. They are also important to the ecosystems of the coastal reefs and shore communities of Florida. I wonder what changes these scientists are seeing in this marine ecosystem. What are the solutions they will propose to the public? How can a balanced management meet the needs of people who live and work there? These are difficult questions to answer.
It is dark when I arrive finally in Key West but a scientist meets me at the airport and drives me to the ship where I find my bunk and spend the night! Everyone has been very kind and helpful which makes participating in NOAA Teacher at Sea even more amazing – if that is even possible!
