The Ghost, Craig Parry’s Photo Of The Famed White Whale Migaloo Won First Place In The Underwater World

Blooms in the Baltic

Every summer, phytoplankton – microscopic plant-like organisms – spread across the North Atlantic, with blooms spanning hundreds and sometimes thousands of miles. Nutrient-rich, cooler waters tend to promote more growth among marine plants and phytoplankton than is found in tropical waters. Blooms this summer off Scandinavia seem to be particularly intense.

On July 18, 2018, the Operational Land Imager (OLI) on Landsat 8 acquired a natural-color image of a swirling green phytoplankton bloom in the Gulf of Finland, a section of the Baltic Sea. Note how the phytoplankton trace the edges of a vortex; it is possible that this ocean eddy is pumping up nutrients from the depths.

Though it is impossible to know the phytoplankton type without sampling the water, three decades of satellite observations suggest that these green blooms are likely to be cyanobacteria (blue-green algae), an ancient type of marine bacteria that capture and store solar energy through photosynthesis (like plants).

In recent years, the proliferation of algae blooms in the Baltic Sea has led to the regular appearance of “dead zones” in the basin. Phytoplankton and cyanobacteria consume the abundant nutrients in the Baltic ¬and deplete the oxygen. According to researchers from Finland’s University of Turku, the dead zone this year is estimated to span about 70,000 square kilometers (27,000 square miles).

One of the major threats to sea turtles is entanglement in fishing gear and other marine debris. 

Each year, threatened green sea turtles make their way to breeding grounds in the Northwestern Hawaiian Islands. Although these islands are largely uninhabited and are protected by Papahānaumokuākea Marine National Monument, ocean currents carry enormous quantities of trash here from around the world. More than 50 tons of debris enters monument waters each year! Here, fishing nets and other debris can entangle breeding adults and young hatchlings. 

You can help protect these and other sea turtles by reducing the amount of plastic you use and participating in beach and watershed cleanups. What actions will you take to protect 🐢?

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.

What’s a whale fall?

Whale falls can be found throughout the ocean. This one was spotted in Channel Islands National Marine Sanctuary, off the coast of Southern California!

What a Nut!— Invasive Species Week

This ctenophore (a stingless jellyfish-like animal) called a sea walnut is native to the east coast of North and South America. In 1982, it was discovered in the Black Sea, where it was transported by ballast water. It subsequently spread to the Caspian Sea. In both places, it multiplied and formed immense populations. The sea walnuts contributed to the collapse of local fisheries because they feed on zooplankton that the commercial fish also consume. Mnemiopsis leidy has also been discovered in the Mediterranean, Baltic, and North Seas.

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.
