Thinking Outside the Box on Fisheries Management? Think Again.

This week, thanks to OpenChannels, I came across an interesting scientific article critiquing a new concept in fisheries management called “balanced harvesting”. Co-authors of the article include prominent fisheries scientists such as Rainer Froese, Daniel Pauly and Sidney Holt. (For ...

Effective marine protection: what does the science say?

The pressing need for the creation of marine protected areas (MPAs) (sometimes called as marine reserves) is discussed often on the Ocean Views blog. MPAs and reserves can help ecosystems recover, provide climate refuges and even protect humans. So we ...

Protecting Antarctic Marine Ecosystems: From Anemones to Whales

Over the past few years, I’ve written a lot about efforts to create marine protected areas (MPAs) in the Southern Ocean. For someone like me, who works on these issues and studies the Antarctic environment, the justification for MPAs ...

Slow Progress in Protecting Polar Waters

  Yesterday, I talked about the justification for imposing new requirements on ships that operate in polar waters. The good news is that countries with major presences in the Arctic and Antarctic agree that such requirements are necessary, and over ...

Little-known Code Could Have a Major Impact on Polar Environments

Scientists recently identified multiple new trans-Arctic shipping routes that will be accessible to non-ice-strengthened vessels in just a few decades., Given that such routes would have been unimaginable a few decades ago, this research is yet another sobering reminder of ...

Antarctica Braces for Influx of Invasive Species

Antarctica and the Southern Ocean may seem very far away from civilization, but they are at great risk of losing their unique qualities due to human activities. Warmer temperatures and human visitation are increasing the likelihood that invasive species can ...

Strong Evidence for Ocean Acidification Impacts in Southern Ocean

For years, researchers have warned that the increasing acidity of the oceans is likely to create a whole host of problems for the marine environment. Most of these warnings were predictions for future decades as well as theories about possible ...

Dying for Some Fish

  By Claire Christian The Ross Sea in the Antarctic brings to mind visions of icebergs, penguins, seals and whales.  Yet, increasingly, the Ross Sea – with its harsh environment of sub-zero temperatures and iceberg-riddled waters – is being visited by fishing ...
