Candidate compass genes in fish

A team of American researchers use next-generation sequencing to ask: “magnetoreception, how does it work?” Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic responses of Fundulus killifish to intermittent […]

Eating bones and building habitats: the life of an ecosystem engineer

Believe it or not, zombies can be…a good thing? Read on to find out how “zombie worms” in the deep ocean contribute to biodiversity! Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on lobsters and how they respond metabolically to ocean acidification projections. I did my undergrad at […]

It’s Getting Hot In Here: How Ocean Acidification and Warming Affect Shark Hunting and Behavior

Elasmobranchs such as sharks and rays face physiological and behavioral changes due to ocean acidification and rising ocean temperatures. Read about how these changes influence how sharks hunt and their role in the marine ecosystem. Aditi TripathyHello! I am an undergraduate student majoring in Marine Biology with a minor in Acoustics at the University of […]

Stressed-out microbes in an acidifying ocean

The ocean is acidifying in response to carbon dioxide emissions, but we are just beginning to learn how this effects the ocean’s most abundant lifeforms – microbes. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in […]

3D printing and oceanography? Check out the fascinating new research advancements made in ocean sciences using one of the most innovative technologies of the 21st century! Prabarna GangulyI’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. My research focuses on the impact of early life stress in the form of […]

After the Phase Out: Can Banning Toxic Chemicals Rescue Pilot Whales?

When it comes to persistent pollutants, all roads lead to the ocean. Perfluorooctanesulfonic acid (PFOS) is a chemical that has recently gained attention due to its toxic effects and widespread presence in drinking water. PFOS from human products has also become widespread in ocean waters and the creatures who live in them. PFOS was banned […]

The Missing Mechanism: How Ocean Fronts Impact Sinking Organic Matter

Phytoplankton are central to the ocean’s carbon cycle, converting carbon dioxide into organic molecules that sink into the sea’s interior. But the ocean is moving and variable. As a result, we don’t have good estimates of how many of these phytoplankton-made molecules exit the upper ocean where phytoplankton reside. Find out how Stukel et al. […]

Can Ecotourism influence sharks?

Article: Barnett, A., Payne, N. L., Semmens, J. M., & Fitzpatrick, R. (2016). Ecotourism increases the field metabolic rate of whitetip reef sharks. Biological Conservation, 199, 132-136. doi.org/10.1016/j.biocon.2016.05.009 It’s no secret that whenever we interact with animals, they change their behavior when around us. Dogs get excited and jump up and down, monkeys come closer to get […]

OceanTech: profiling the sub-surface via Argo floats

The final post of theme week introduces the Argo array, an international effort to understand the ocean’s sub-surface via technological floats that enable continuous, real-time temperature and salinity data collection. Data collected from the Argo array can be coupled with satellite and shipboard measurements to provide a more complete understanding of global ocean dynamics. Anne […]

TBT Old School Ocean Tech: Simple Sampling Gear

Sometimes it’s the simple things in life that make it all worth it! Well, it may just be me, but I love using the tried and true old school sampling gear, despite all the complex gadgets and gizmos that seem to be developed faster than I can learn about them. In today’s ocean tech post, […]

Under the Sea(floor): Ocean Drilling and Scientific Discovery

Deep, dark, and mysterious, the ocean seafloor contains clues and records of past life and climates on earth. Understanding the subseafloor is critical to understanding our planet. But how do we reach these muds and rocks that lie beneath? Here we explore the history of subseafloor exploration, and find out about some of the technologies […]

Mucus flux and other amazing discoveries with underwater cameras

Scientists have been taking pictures underwater since the turn of the 19th century. But only recently have researchers and engineers started designing special systems to answer some of the most vexing questions in oceanography. Just last week, a group from MBARI published their findings from one such instrument about zooplankton mucus. Eric OrensteinEric is a […]

Ocean Tech: Using Robots to Conduct Deep-Sea Research

The deep sea is the largest habitat on Earth, but with freezing water and high pressures it is difficult for scientists to study this ecosystem. With the help of technological advances over the past decades, it is becoming easier to unveil some of the mysteries of the deep. Read on to find out how. Ashley […]
