Fun Science FRIEDay – Visualize the Seafloor

November 4, 2016November 7, 2016 Kersey Sturdivant

Happy FSF! As some of you may know (and for those who don’t), I study the bottom of the ocean, and I do so primarily using innovative technology to image the seafloor (e.g., Wormcam). The interesting work I’ve conducted has resulted in me having the opportunity to present my work to a larger lay audience, in the form of a TEDx presentation.

I am giving my TED talk with my good buddy and colleague Steve Sabo. In our talk, “A Picture is Worth a Thousand Worms”, Steve & I will illustrate the significance of the ocean floor through advancements in underwater camera technology and data visualization, making complex science more accessible for everyone.

Fun Science FRIEDay – Underwater World of Pollination

October 14, 2016 Kersey Sturdivant

Science

Pollination. I think most people understand why this is important (or maybe I should say, I hope). To put it simply, the process of pollination facilitates reproduction in plants by transferring pollen from one plant to another. In the terrestrial world, this can be mediated by physical forcing (e.g., wind) or by animals (e.g., insects) – and its why people are freaking out about the loss of bees due to pesticides (because they are a primary pollinator), but I digress. Until relatively recently, pollination by animals was not thought to occur in the ocean. Unlike on land, where most flowering plants rely on creatures to carry pollen, plant reproduction in an aquatic world was surmised to rely exclusively on currents and tides. However, a team of researchers led by marine biologist Brigitta van Tussenbroek revoked the long standing paradigm that pollen in the sea is transported only by water, discovering and documenting the process of zoobenthophilous pollination (a term they coined).

Fun Science FRIEDay – Drug Resistant Bacteria, The Movie

In today’s FSF we bring you both a jaw dropping, and somewhat terrifying cinematic visualization of how bacteria evolve resistance to antibiotics, and overtime can become super bugs immune to any antibiotic treatment. A concise and detailed description is presented below:

This stunning video of evolution in action captures how bacteria with no resistance to an antibiotic can in a very short time become resistant to concentrations of more than a thousand times the initial concentration. Other scientists have documented this phenomenon before, but never with such vivid clarity as that provided by Michael Bay and Roy Kishony of Harvard University.

Fun Science FRIEDay – Shark Daycare

A great white shark nursery in the North Atlantic that was discovered in 1985 south of Cape Cod in the waters off Montauk, New York has received renewed attention due to the increased activity of white sharks off cape cod in recent years. The nursery was first documented in 1985 by Casey and Pratt who deduced the presence of a nursery based on the number of juvenile sightings and landings in the area. This work was followed up recently by OCEARCH (an organization dedicated to generating scientific data related to tracking/telemetry and biological studies of keystone marine species such as great white sharks), which tagged and tracked nine infant great whites to the nursery, located a few miles off Montauk.

Fun Science FRIEDay – Glaciers Lost in Time

Human induced climate change is real. It feels weird that I have to say that, but the overwhelming body of evidence suggest human activity post the industrial revolution is having irrevocable damage on our environment. One of the major implications of climate change is the loss of the polar glaciers (and subsequent sea level rise).

Oceanography for Everyone, Open Science, Uncategorized

The oceans belong to all of us. With this simple statement in mind, the Oceanography for Everyone (OfE) project was launched with the goal of making ocean science more accessible. One of the biggest hurdles in conducting ocean science is instrumentation costs, and 4 years ago the OfE team began trying to make one of the most basic ocean science tools, the CTD (a water quality sensor that measures Conductivity-Temperature-Depth), cheaper… much, much cheaper!

The Importance of Scientific Discovery and Communication for a General Science Audience

June 3, 2016June 3, 2016 Kersey Sturdivant

Education

The impetus for this piece was an essay I wrote for iBiology a year or so ago discussing the importance of scientific discovery for a a general science audience (i.e., our science peers who are not in our respective field). I was excited to write the piece because a lot of the Science FRIEDay articles I write focus on relatively recent scientific discoveries, and this article is more of an opinion piece. So why is scientific discovery important for an audience of science peers who do not explicitly work in our specific field?

It is easy to marvel at the wonders that exist on our planet and in the surrounding universe, the known discoveries. As a natural scientist, I also appreciate the beauty in the hidden mysteries of the natural world, those processes, behaviors, and functions that we have yet to elucidate. The notion and concept of scientific discovery is romanticized as a purist’s deed. Edwin Hubble said it best, “Equipped with his five senses, man explores the universe around him and calls that adventure Science.” A scientist’s basal desire is to further the state of knowledge, but equally we crave information about the fields of knowledge that are expanding around us, of which we are not explicitly involved. We aspire to understand the “99%”, at the very least surficially. The importance of this desire explains why scientific conferences play a major role in our profession, and journals such as Science and Nature are so popular. Yes, we as scientist want to share our new discoveries, but we are also equally as intrigued about what others have accomplished; we want to know how science is progressing outside of our bubble, especially those really groundbreaking feats. These coupled characteristics are a necessary component of science. Hearing and learning about the work of others fuels one’s own scientific passions to go and do more, and can often challenge an individual to think more creatively about their own research ideas and approaches. To a general audience of our scientific peers, sharing scientific discovery temporarily satiates the yearning that scientists have about the progression of knowledge, but also can serve as motivation and inspiration.

Fun Science FRIEDay – The worlds largest sponge.

Recently a team of scientists on a deep sea expedition in the Northwestern Hawaiian Islands aboard the R/V Okeanos Explorer made a monumental discovery… pun intended. While exploring the depths of the seafloor in Papahānaumokuākea Marine National Monument, with their remotely operated vehicles (ROV) Seirios and Deep Discover, they discovered and documented the largest sponge ever observed on this planet… or any planet for that matter.

Do you ever get that feeling that you are being watched? I imagine that is what the ospreys at the nesting platform at the Virginia Institute of Marine Science (VIMS) must feel, if they notice at all. These birds have a camera that is trained on their nest 24/7 during the osprey breeding season (generally from mid-March … Read More “Fun Science FRIEDay – Osprey Version of the Truman Show #ospreycam” »

Roughly every few Thursdays the Condon Lab at the University of North Carolina Wilmington host an “Who Am I” Throwback Thursday. The premise is to expose people to scientist who have had a measurable influence in their respective fields. We will start broadcasting those Who Am I at Southern Fried Science. This week features one … Read More “Throwback Thursday – Who Am I?” »
