Small boats drowning out natural reef noise?

Don’t you hate when noises interfere with your daily activities and conversations? We create lots of noise in the environment and need to know more about it. Today’s oceanbites focuses on a study of man-made noise on coral reefs. Check it out! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]

Tracking the movements of a heavily fished Fijian shark

The silvertip is a reef shark targeted for its fins. Scientists tagged a Fijian silvertip to learn more about what depths and temperatures it likes to hang out in. Lis HendersonI am studying for my doctoral degree at the Stony Brook University School of Marine and Atmospheric Sciences. My research addresses fisheries and climate change […]

Making potable water safe for the seafloor

SWRO desalinization is a great way to get potable water. Unfortunately its production results in a high salinity low nutrient discharge that impacts the benthic communities. This study shows how a simple mitigation effort can reverse damage from discharge in just months! Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine […]

Wake-up Call: Global Oceans in Big Trouble!

Our global oceans are in a state of crisis. A new report from the WWF paints a bleak picture: human interference has pushed the oceans to the brink of collapse. The health of marine organisms and the habitats they live in have become severely threatened by compounding factors such as pollution, overfishing and increased CO2 […]

Taiwan creates “Facebook” for sea turtles!

Photo ID databases have been used to estimate population sizes for zebras, cheetahs, whales, sharks dolphins, turtles and more. This tool has now spread to a new area. Introducing the first animal photo ID database in Taiwan for green sea turtles! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University […]

Just sealing around; Ice seal misidentification in aerial surveys

Aerial photographs are a great way to collect images of marine species in order to analyze their distribution patterns. Distinguishing different species is difficult, and unfortunately this leads to the misidentifictation of several species. This is the case for ice-associated seals, species for which global climate change has motivated intensive monitoring efforts in recent years. […]

Protecting Well-Traveled Fishes: A New Approach

Fisheries managers have begun a shift from attempting to protect individual fish species to protecting entire ecosystems. Marine Protected Areas (MPAs) have been highly successful at conserving important species and habitats like coral reefs. Is it possible to utilize relatively small MPAs to protect the 200-300 fish species that regularly travel long distances? New research […]

A new thermally tolerant species of algae is found!

Rising ocean temperatures threaten coral reefs, but a new thermal tolerant algae could help. Valeska UphamFor my fisheries and aquatic science PhD I am working on how to tank raise urchins and transplant them onto reefs across the Florida Keys in order to help reverse the phase shift from algae dominated back to coral dominated.

There are plenty of fish in the sea! ….or are there?

Tigers, pandas, and orangutans are the poster children of endangered species, but marine animals have started to join their ranks. Scientists compared the terrestrial extinction events to more recent marine animal depletions to try and predict potential threats to marine ecosystems. What they found may help us to prevent large scale extinctions from occurring in […]

Watch out guys, pregnant whale sharks are on the loose!

Whale sharks have become an increasingly popular tourist attraction, but much of their life history remains largely unknown. This study sets off to observe whale sharks around Darwin Island to help understand more about their habitat use, population size, and seasonal appearances. And what they find is a whole lot of pregnant whale sharks. Valeska […]

Can a complex model hold the fate of the crown-of-thorns starfish?

Not all starfish are cute! The crown-of-thorns starfish has been eating all the coral on the Great Barrier Reef! Researchers set out to build a model in hopes of demonstrating the trophic interactions between this dangerous starfish and its prey, the coral. Valeska UphamFor my fisheries and aquatic science PhD I am working on how […]

The Great Barrier Reef is worth $15 billion – $20 billion AUS a year: A quick lesson in ecosystem economics

When discussing the value of an ecosystem, tensions run high. Some people evaluate ecosystems with heavy emphasis on non-use values, like aesthetics and spiritual appreciation. Other people value ecosystems based on things like natural resource availability and the potential for direct monetary revenue. It is difficult to assess the relative importance (or value) of these […]

Supermom of the depths: octopus guards its eggs for the longest period ever observed

Scientists found an octopus that guards its eggs for the longest period ever recorded. The super mother was filmed for 53 months and has produced the largest and most developed hatchlings known to date. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how […]

Are whale sharks in trouble?

A recent study at the global scale suggests that there are two distinct populations of whale shark (Indo-Pacific and Atlantic Ocean). Authors show the evidence that populations of sharks aggregating at Ningaloo Reef in Western Australia have been declining in genetic diversity from 2007 to 2012. Catarina SilvaHi! I am a PhD candidate at Victoria […]

The far-reaching benefits of marine reserves

It can actually work! A recent multidisciplinary study combining genetics and modeling conducted in the marine protected area of Torre Guaceto, Italy shows how effective marine reserves can be. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the environment influences genetics. Check […]
