Goodbye sound, hello vision: less $$$ methods to help Unmanned Underwater Robots stay on track.

Goodbye sound, hello vision. Robots become better navigators thanks to a group of scientists in Mexico who applied an alternative way to help unmanned robots regain their position and orientation when they get forced off task. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky […]

A change in ocean circulation makes for long glacial periods through the Mid-Pleistocene Transition

Isotope records from the Southern Ocean imply that prolonged epochs of time between glacial and interglacial periods through the Mid-Pleistocene Transition were caused by a reduction in deep waters mixing with the surface and the positive feedback it created with the salinity gradient. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a […]

9 Useful tips from an Alan Alda Science Communication Workshop

9 Lessons from an Alan Alda Communication Workshop that will help transform presentations overpowered by long-winded jargon-rich sentences into ones that send a concise and memorable message. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky to have had many roles in my neophyte career, […]

The real-time impact of ship noise on dolphin calls

Dolphins are not alone in their adaption to noisy surroundings. Understanding the long-term sustainability of these animals ability to communicate with each other with altered calls is important for establishing meaningful protections for them as greater levels of noise are introduced into their surroundings.

Tips from a workshop on Negotiating

Negotiating is a valuable skillset that many scientists are never formally trained in. This post highlights some of the take away messages from a Strategic Persuasion and Negotiating workshop I attended last week (November 13, 2018). Anne M. HartwellHello, welcome to Oceanbites!

New technology inspired from ancient art

When scientists find new applications for old ideas, they can open up a world of possibilities. A group of researches from around the USA teamed up to design a catch-and-release sampling device inspired by origami that will help them explore the diversity across mid-ocean depths. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, […]

Outreach- Ship to Shore STEM education

Delivering field work directly from the field to the classroom has become an important part of science communication and engagement. This post introduces a great learning tool called Adopt a Microbe- a fun and engaging project and website designed to bring microbes and marine science inside the classroom. Anne M. HartwellHello, welcome to Oceanbites! My […]

Octopus Mama Drama: Research Expedition Bonus Science

Dorado Outcrop is a small underwater mountain that first received attention from a few scientists because the seafloor that it sits upon is colder than what is expected. It ended up in the media spot-light because of the hundreds of octopuses that call it home. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, […]

The Efficiency of Nautili

Imagine if you could function just as well at the top of Mt. Everest (where the air is super thin) as you do at sea level; you’d probably be considered pretty special. Well, nautiluses can do that, and these researchers wanted to know why. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m […]

Biofilms are a prominent first step in the colonization of wood-falls

A profound yet never-before-appreciated first step in the colonization of sulfur oxidizing bacteria on the surface of wood-debris in the deep-sea is attributed to sugars and other labile components of wood.

2018 Society for Women In Marine Science Spring Symposium

This past Saturday, the Society for Women in Marine Science URI chapter hosted their first spring symposium.  The event offered active discussion about issues relevant in science while encouraging the participation and success of women in marine sciences. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has […]

Incubation station: are hydrothermal vents speeding up skate-egg development?

Are skates using warm vent water to incubate their eggs? Researchers claim that they have found a direct relationship between temperature and incubation time for skate eggs at hydrothermal vents sites in the Galapagos. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky to have […]

Autonomous Under-ICE Vehicles

Seafloor exploration in areas of thick ice coverage has many obstacles. With careful planning and modifaction of AUV design and recovery methods, explorers are able to map and study the Gakkel Spreading Ridge 4000 meters below the thick Arctic Ice Pack. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research […]

MAC-EXP: A new sediment corer designed to maintain in situ pressure conditions

The MAC-EXP, a pressure-coring experimentation and cultivation system, was designed to advance our ability to analyze the microbial processes in the deep-sea sediments, which is typically a challenge because the pressure change upon recovery can alter the in situ state. Jackson et al. (2017) describe the result of the systems first field trials. Anne M. […]

the Soul of an Octopus by Sy Montgomery

The soul of an octopus: a surprising exploration into the wonder of consciousness by Sy Montgomery is a excellent non-fiction story about getting the author’s experience getting to know herself and the world around her through the unexpected bonds with octopuses. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research […]

Heat flux from active crust

Researchers generate a high resuliton 3-D model of the subseafloor to learn more about what controls heat flux from the Juan de Fuca Ridge! Their findings provide evidence that support hypotheses about the impact of magma replenishment and permeability on heat flux. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine […]

Metal fingerprints enhance recycling

The bioaccumulation of bioactive metals in top predators plays a key role in the recycling of nutrients in HNLC zones of the Southern Ocean. Furthermore, the concentration of bioactive metals can be used as a ‘fingerprint’ to identify the appropriate trophic level of a species. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, […]

Happy World Oceans Day!

Happy World Oceans Day! A day to celebrate and appreciate the fantastic oceans, while also raising awareness of the importance of minding and minimizing our impacts. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky to have had many roles in my neophyte career, including […]

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 […]

Benthic biology on a thermally boring deep-sea ridge

The deep ocean is vast and full of neat ocean dwellers, many of which scientists know little about. One way to investigate them is from images and videos captured during deep-sea exploration efforts using submersibles. A group of scientists did just that to quantify the benthic assemblages at different depths and a variety of substate […]
