a Whale’s tale

Age estimations of marine mammals are traditionally made with a single tooth. A group of scientists from Australia think they can improve the traditionally method by adding more teeth into the equation. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky to have had many […]

Vacancy at your local kelp forest

A diverse community of seaweeds, snails, sponges, crustaceans, and more, find refuge and food within the dynamic kelp ecosystem. Katherine BarrettKate is a 3rd year PhD candidate in the Biological Sciences Department at the University of Notre Dame, and holds a Masters in Environmental Science & Biology from SUNY Brockport. She studies benthic-pelagic ecosystem linkages […]

Methane on the dinner menu

Bacteria in coastal waters can eat methane, a greenhouse gas – but just how much and how fast can they eat? 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 the seafloor, and what are they […]

Take my breath away: Decline in oceanic oxygen levels fifty years in the making

Most marine organisms require dissolved oxygen to sustain their survival. So what is the current status of oceanic oxygen levels? Read on to learn about the oft under appreciated resource of our planet! Prabarna GangulyI’m a fourth year PhD candidate in the Department of Psychology at Northeastern University. My research focuses on the impact of […]

Is the Deep Ocean Warming Too?

It’s been shown that the surface of the South Pacific Ocean has been warming by absorbing excess heat from the atmosphere, but is this heat making it down to the deep ocean? Deep-ocean warming can lead to more rapid global warming in the future, but detecting it is tricky. Despite the challenges, a team of […]

Now You See Me, Now You Don’t: Using an Invisibility Cloak for Deep-Sea Camouflage

You may not have to go to Hogwarts to find an invisibility cloak of your own. Although, the trip to this extreme environment full of transparent crustaceans may be just as tricky to get to. Read more to find out how hyperiid amphipods are able to make themselves invisible! Ashley MarranzinoI received my Master’s degree […]

Dawn of the age of Aquarius…total alkalinity measurements

While not as exciting as the new era of peace predicted by 5th Dimension, it is pretty cool that scientists can measure ocean chemistry from space. The marvels of modern technology, amiright? Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for Underwater Imaging focuses on […]

Seagrasses reduce the risk of disease outbreaks

Seagrasses are one of humans’ greatest sidekicks. They are nursery areas for many species including commercially important ones, they protect coastal communities from extreme weather, they absorb carbon dioxide and release oxygen via photosynthesis and much more. Now, research shows that seagrasses can also reduce rates of disease in humans, fishes and invertebrates such as […]

Cervezas del Oceano

Traducido y modificado por SANDRA SCHLEIER, Artículo original por ERIN MCLEAN Como una persona que aprecia mucho la cerveza, podemos decir que cualquier día de fiesta, como el Día de San Patricio (St. Patrick’s Day) es una maravillosa excusa para beberla. Uno de mis pasatiempos favoritos y el de mi compañera quien escribió este artículo, […]

Throwing Babies out with the Sea Ice: Ringed Seals Response to Ice Decline

As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I […]

‘The conservationist is ready to see you’: triaging marine ecosystems in times of climate change

Climate change affects ecosystems worldwide, but how do conservationists decide which of planet earth’s ecosystems are most in need? Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.

An Ocean in Your Beer

This St. Patrick’s Day, think outside the green beer and whiskey and try an ocean-inspired beer! Didn’t know there were beers brewed with ocean life? Read on to learn more about how our oceans and your beer are intertwined. Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on […]

Looking into the crystal ball of statistics, or how number crunching debunks the natural variability argument skeptics love

Have that one relative who always argues that current climate change symptoms are part of natural variability? Check out this article and be prepared with some nifty statistics next time they try to make that claim! Anna RobuckI am a third year PhD student at the University of Rhode Island Graduate School of Oceanography in […]

More than cow burps: the many sources of methane

Methane is an important, and often forgotten, greenhouse gas. It comes from a variety of sources including wetlands, rice paddies, and natural gas operations. This article explores methane’s role in our changing climate and investigates some natural and anthropogenic sources. Victoria TreadawayI am a PhD candidate at the Graduate School of Oceanography at the University […]

Life Finds a Way: Eelgrass Beds Respond in Surprising Ways to Extreme Warming Events

Article: Reynolds LK, DuBois K, Abbott JM, Williams SL, Stachowicz JJ (2016) Response of a Habitat-Forming Marine Plant to a Simulated Warming Event Is Delayed, Genotype Specific, and Varies with Phenology. PLoS ONE 11(6): e0154532. doi:10.1371/journal.pone.0154532 Climate change is poised to dramatically alter the make-up and functioning of Earths’ ecosystems, including those in the oceans. […]

So cute!

It’s a trap! African penguins impacted by climate change

Young penguins living along the southwestern coast of Africa typically follow cool, nutrient rich water to find food as they grow up. This used to lead them to ‘delicious’ fish such as anchovies and sardines. However, in this ecosystem – the Benguela Upwelling Zone – climate change and overfishing have reduced these fish populations. This […]

¿Deberíamos prohibir toda pesca de tiburones?

Traducido por Sandra Schleier, artículo original por MEGAN CHEN Artículo: Simpfendorfer, CA, Dulvy, NK (2017).  Bright spots of sustainable shark fishing.  Current Biology. 27:R83-R102.  doi: dx.doi.org/10.1016/j.cub.2016.12.017 El Reto: Intenta nombrar todas las especies de tiburones que puedas. Aunque solo tendemos a pensar en los tiburones blancos, martillos y toros, existen sobre 1,000 especies de tiburones y sus […]

Hunter-Chiller: Multiple feeding strategies for some of the world’s smallest organisms

Because of their ability to conduct photosynthesis, most of our planet’s oxygen comes from microscopic organisms in the ocean called algae. In addition to photosynthesis, some of these algae can also hunt and consume prey to supplement their energy needs. In this study a group of scientists has set out to determine just how their […]

Oceans absorb more carbon with weaker ocean circulation

A team of researchers investigate why the ocean has been absorbing more carbon from the atmosphere in recent decades, and find ocean circulation could be responsible. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in climate. For […]

Now we got bad blood: Oxygen binding is not affected by haemoglobin subtype in Atlantic cod

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 […]
