Not Every Creature In The Ocean Is Cute And Cuddly – Some Are Downright Spooky! 

A shark on a reef is a definite sign that the reef is healthy! Years ago people were terrified if the saw a shark, now were horrified that we may not see sharks on the reef or anywhere, because we have killed over 90% in the last 50 years. We must end to this needless slaughter! Sharks are essential to keeping our oceans healthy and in balance! The oceans are the heart of our planet! Over 50% of the air we breath and 70% of the protein we eat comes from the ocean. Without our the ocean all life on this planet will die. Please be the change the world needs to survive!

What will scientists find in the deep waters off California?

Deep-sea corals and sponges are some of the oldest animals on Earth, living for hundreds of years at depths beyond direct human observation. Coral, sponge, and fish communities thrive in the cold, deep waters off California’s coast, but are rarely – if ever – visited or observed.

In late July and early August, scientists using advanced technology aboard the NOAA Ship Bell M. Shimada will study unexplored seafloor habitats off North-Central California in NOAA’s Greater Farallones and Cordell Bank national marine sanctuaries. Their focus includes coral, sponge, and groundfish communities. What they learn will help inform the management of these special ocean areas, and add to knowledge about deep-sea habitats and the biological communities that live there.

Using a robot to explore the deep

To survey the seafloor and record images of the habitats as deep as 2,000 feet (600 meters), scientists are using a remotely operated vehicle (ROV), launched from the ship and sent into the depths of the ocean. In addition to sending real-time video and images via a cable connected to the ship, the unmanned ROV will collect geological and biological specimens for identification. Scientists will also conduct seafloor mapping, an important tool for management of marine areas.

Why journey to the deep?

The deep sea is vastly unknown because it is largely inaccessible by humans. However, it affects us in many ways. A healthy ocean is essential to the health of our planet, and deep-sea communities are an important part of marine ecosystems. The deep sea nurtures fish stocks and hosts life-forms like bacteria and sponges that have contributed to medical discoveries.

Coral and sponge habitats are among the most biodiverse and productive ecosystems throughout the entire ocean. Increasing global human demand for resources has created a need for expanded science and conservation of these deep-ocean ecosystems and the benefits they may yield. Both living and dead corals and sponges are “biogenic habitats,” where the organisms themselves provide habitat for other marine life.

Previous NOAA expeditions off California’s coast have identified several new species of corals and sponges, including Swiftia farallonesica, a slender white coral, in the deep waters of Greater Farallones National Marine Sanctuary, off the Sonoma County coast. New sponge species were discovered living on the wreck of the USS Independence off the San Mateo County coast. They were also discovered in Cordell Bank National Marine Sanctuary, both in Bodega Canyon and on the deep slope near Cordell Bank to the north. New species discoveries indicate that we still have much to learn about the deep sea.

The ocean supports hundreds of billions of dollars of the U.S. economy through food, jobs, transportation, recreation, and other services. NOAA’s mission is “to understand and predict changes in climate, weather, oceans, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources.” Assessing the conditions of ocean ecosystems can lead to better management of those areas to support the ocean economy.

Stay tuned for more pictures and information after the expedition!

These microscopic beauties are foraminifera—single-celled organisms that live in the ocean. Since they make their shell using oxygen from the water, as ocean temperatures fluctuate through time and change the type of oxygen in the water the shells’ structure also changes.  Paleontologists like the Smithsonian’s very own Brian Huber can use fossil foraminifera to track changes in Earth’s climate from over 540 million years ago.

Covering the oceans in darkness….

Phytoplankton blooms produce some fascinating textures in Earth’s oceans, and consequently we’ve shared images of them taken from orbit many times (http://tinyurl.com/qhzwbr9, http://tinyurl.com/pwasxol). This bloom, however is a bit different from the others – in this photo from NASA’s Aqua satellite, it looks, well, black.

Adjustments to a different educational landscape

Different systems

Less work

Difficulties

I thought it would be appropriate to write about the different educational landscape after taking my first round of exams for a number of reasons. First, it gives me enough time to adjust (kind of) to the different system, and secondly, it gives me a bit of time to reflect on the system as well.

I'll begin with a brief description outlining different education system. First, most students do not live on campus. Some may live two or three hours away too, which makes me feel awkward when I say I live on campus because the two hour is too long to do two times every day. Second, most classes are only once a week, which can make it easy to forget about work and procrastinate. In fact, my only class that is two times a week is my Spanish class taught by a professor with IFSA-Butler.  

In my classes, there is a lot less "busy work," which is bitter sweet for me since busy work helps me stay on top of content but at the same time reduces free time. This also translate into less exams. In each of my three classes that have exams, there are only two. There is a lot of group work, usually including presentations, but in one of my biology labs, it means a lot of lab/field work. In the same course, called Evaluation of Habitat, we had two weekend trips (one to a refuge and one to a biological reserve) to complete small, independent projects.

Adjusting to this new academic system is difficult, especially with the language barrier. I also think that since there fewer numbers of classes every week, it is a lot harder to get a feel for each professor. It is difficult for me to point to few particular skills that I gained during my first year of college that I have used here because for me, I always need to experience it for myself and then I find my footing. It is hard to do it quickly, but I think that the best way for me to make the transition is to simply immerse myself in the system and my work.

IFSA-Butler's main role, especially during orientation, was giving advice to all of us and letting us know that they are there to provide support to us, including offering free tutoring to anyone who wanted it.

That was rather impressive
