Science and Technology Log
It is easy to see why the Earth is nicknamed the Blue Planet. Its dominant physical feature is the sea water which covers approximately 70% of the surface making it appear blue even from space. People have depended on the oceans for centuries not just for the obvious things such as food, transportation, jobs and recreation but also for the very oxygen we breathe and the fresh water we drink to survive. Humans need the ocean for all these things and more. We are inextricably interconnected to the ocean; our survival depends on it.
The vastness of the ocean allows us to believe that human actions won’t have a major effect on it. For example, pollution that leaks into the ocean would be diluted by the huge amount of water so that no real harm would be done to the habitat or the organisms living in the ocean. This may have been true for a time when the human population was less than the 7 billion people now living on Earth. However, the fact is human actions do influence the ocean and in ways that matter. Often these impacts are unintended or accidental but they still lead to a change in the marine ecosystem. Sadly, many times these effects are negative such as the Deepwater Horizon/BP MC252 oil spill In 2010, an explosion on an oil drilling rig in the Gulf of Mexico released almost 5 million barrels of oil into the ocean immediately changing the marine habitat and harming the organisms that lived there. Scientists are still determining the long term effects of this spill and helping to restore the area. In the past other spills have occurred such as the grounding of the oil tanker Exxon Valdez in 1989 that released 11 million gallons of crude oil along the Alaskan coast.
Not all ocean impacts are large events related to the petroleum industry. Even small individual human decisions can be significant. For example, if a pet owner no longer wants to keep his exotic species pet he might release it into the wild or an environment where that organism isn’t usually found.
This is probably how the Lionfish, scientific name Pterois volitans, has become established in the coastal waters near the Carolinas and Florida, according to Paula Whitfield, a NOAA marine scientist. It may seem like a minor problem that the Lionfish is now living in Gulf Coast ocean water. What do you predict will happen to the number of Lionfish in this area knowing that they have everything they need to flourish: food, water, space but no predators to hunt them? They will reproduce and increase their numbers quickly. Lionfish will out number native species of fish and beat them out for those resources displacing them in their ecosystem. Lionfish will out compete native species decreasing their numbers and the diversity of organisms. While on our cruise the science team encountered groups of Lionfish living under large rocks at depths of 100 feet. They speared a specimen and brought it aboard to examine it closely. Lionfish are invading this marine habitat taking it over from the native species. Any organism that is introduced into a new ecosystem where it can rapidly increase numbers taking over native habitat is called an invasive species. One solution to this problem is to start catching Lionfish to eat! I am told they are yummy. People just need to be taught how to safely remove their poisonous fins and taste them!
Both animal and plant organisms can be invasive species squeezing out more desirable native organisms. In Nevada, we are on the alert to an invasion of Quagga Mussels (Dreissena bugensis) that have been detected in Lake Mead near Las Vegas. These fresh water mollusks are transported on boat exteriors or in bilge water to other fresh water lakes across the United States. It is important that boaters carefully inspect and maintain their equipment to halt the progress of this invasive species to other lakes in Nevada and elsewhere.
The Blue Planet is home to us all. Our decisions and actions make a
difference on both a small and large scale. Each of us has a responsibility to make informed choices about these actions. Realizing our reliance on the ocean and other aspects of the environment and working within in these systems really benefits all of us. For example, when architects designed the Dr. Nancy Foster Florida Keys Environment Complex in Key West, Florida they created a Green Building. This means they made choices to “recycle” a neighboring building saving building materials and using it for a new purpose. Office furniture was re-purposed to fit in the new energy efficient building that is LEED Silver certified. Contributing to the ecosystem, the roof is planted with native species of grasses that provide habitat for insects and birds. The plants are watered by rain. Excess rain water is collected and stored for other uses in the building helping to conserve water. While the Dr. Nancy Foster Complex building design is indirectly related to ocean preservation it represents a human action that benefits our Blue Planet. As with the release of a hand full of Lionfish, so can many small actions together can create a big impact. Choose to be connected to our ocean in a positive way. Through a small act you do each day we can preserve and even improve our environment and oceans. The Blue Planet is a great place to call home. Let’s help keep it that way.
Personal Log
As I finish writing this last blog from my home in Reno Nevada, I am reflecting on the many people I have met and the experiences I have had as a NOAA Teacher at Sea. It is through NOAA’s interest in connecting scientists, mariners and educators that I was able to participate in this amazing experience but also because I took a chance and applied. I might not have been chosen but I didn’t let that stop me from taking the risk. If I had not made the time to apply and prepared my essays and sample lessons look what I would have missed. The chief scientist, Scott Donahue, also took a chance on me and accepted me as an active participant on his research cruise. He and the science team went out of their way to make sure that I stayed safe and got an outstanding experience as an observer of their research. Everyone took time to answer my questions and describe their research to reach a larger audience, YOU!
On the last day we sailed into port at Key West, few people aboard knew that
Ensign Richard de Triquet was given the task of bringing the NOAA Ship Nancy Foster into dock. It was his first time to manage this procedure! Commanding Officer LCDR Holly Jablonski knew he had the skill and took a risk assigning Ensign De Triquet to maneuver the ship into port. Working as a team, the other officers on the bridge used binoculars to spot potential obstacles in the channel. They discussed the best course for the ship and provided input to Ensign De Triquet who announced the orders. By the way, the docking was was smoothly accomplished and I got to observe the entire process including the debriefing. Congratulations Ensign De Triquet, nice work!
My NOAA Teacher at Sea experience is one that I will never forget! It was a pleasure to be a part of this science research cruise and to
meet such a wonderful group of people. My blog would not be complete without acknowledging several individuals in the group who were especially helpful. Danielle Morley who cheerfully provided me with an overview of the VR2 research including a power point presentation and got me involved in the data collection. Hatsue Bailey who acted as my photographer whenever needed. Sarah Fangman who provided ground transportation. Alejandro Acosta, PhD who took me snorkeling after a tour of Ft. Jefferson in the Dry Tortugas. He also was the underwater photographer of the organisms we saw that day. Thank you, everyone!
Just as people are interconnected to the ocean they are also interconnected to each other. All of the people I met on this adventure worked together toward a common purpose. Each one of them making their own contribution to reaching that goal. They did it by doing their best work and trusting that each member of the group would in turn do their part to their best ability. Effort and communication were key to their success. From what I witnessed it worked out perfectly.
Summer is quickly coming to an end and with it the excitement of a new school grows. My students and I have the opportunity to make connections, to each other, to the Blue Planet and the organisms that live here. This year, if you are faced with a challenge, be brave and take it on. Assess an opportunity and take the risk to try something unfamiliar. Extend kindness to someone outside your existing circle of friends. Put your toe in the water and get comfortable listening, observing, thinking and asking questions. You will be amazed what you will learn and the things you will experience. Take a chance. Reflect, communicate and work together. Scientists and NOAA Ship Nancy Foster officers and crew showed how well this works to get the job done. Let’s follow their example so that your 7th grade year in science a memorable one too.
