Ocean surface waves play an important role in maintaining the marginal ice zone, a heterogenous region occupied by sea ice floes with variable horizontal sizes. The location, width, and evolution of the marginal ice zone are determined by the mutual interaction of...

Areas covered in compact sea ice are often assumed to prohibit upper ocean photosynthesis. Yet under-ice phytoplankton blooms (UIBs) have increasingly been observed in the Arctic, driven by anthropogenic changes to the optical properties of Arctic sea ice. Here we...

The coupled interaction of ocean surface waves and sea ice is important in determining the thermodynamic and dynamic properties of sea ice and its relationship to the ocean and atmosphere. Wave-ice interactions create the marginal ice zone (MIZ), a region critically...

We speculate on a marine future for New Zealand and how, as a society built upon a foundation of maritime endeavours, it could benefit from a re-engagement with the ocean domain. Specifically, we suggest that by embracing a rapidly, globally and radically evolving...

Ocean waves are a massive source of energy, but it’s challenging to design power generators for the harsh environment. Allowing marine organisms to grow on engineered structures could help. Link.

There remains much to be learned about the full range of turbulent motions in the ocean. Here we consider turbulence and overturn scales in the relatively shallow, weakly stratified, fast-flowing tidal flows of Cook Strait, New Zealand. With flow speeds reaching...

Researchers have surveyed an Antarctic under-ice river for the first time directly, and their observations support the idea that such sub-glacial rivers form estuaries as they flow into the ocean. Link.

Most of the ocean is very cold (average temperature is just 4C!) and most of that cold water comes from the shallow seas next to the Antarctic coast. In a recent paper (https://www.nature.com/articles/s41598-021-81793-5) it is shown show that the very dense water is...
