It's a story of the warm and the wet.

NIWA has developed a new method for spatially-explicit, quantitative, sustainability risk assessment of pelagic shark population.

Sharks are vulnerable to overfishing because of their low reproductive rates and often low growth rates. Most pelagic sharks fall near the middle of the shark productivity scale, and there is concern that catching too many of them could lead to population depletion. In New Zealand waters, mako sharks are the second most commonly caught shark species (after blue sharks) on tuna longlines.

Warrick Lyon is heading to the Marshall Islands to teach fisheries observers how to tag sharks.

The hard concrete surfaces that characterise New Zealand towns and cities are barely likely to register as a problem with most people. But they're never far from the minds of our urban water researchers.

Methods/tools that can be used to assess ecological flow requirements in rivers with varying degrees of hydrological alteration and instream values.

One of the world's leading scientific publishers has named a paper cowritten by a NIWA scientist as one of 250 groundbreaking findings that could "help change the world".
