Recent studies expand our understanding of the diversity, distribution, and resilience of species from polymetallic nodule fields.

The last half year saw a slate of great studies highlighting the diversity, distribution, and resilience (or lack thereof) of the animals that live in polymetallic nodule fields. While there are many, many more, we have selected a cross-section of the more unusual and unexpected findings. Sponges Sponges, particularly glass sponges, may prove to be […]

New Depth Limit for Deep Sea Marine Burrows

Hydrothermal vents are used as nursery grounds for non-vent animals.

One of the most tantalizing emerging trends from the last half year are new studies showing connections between ecosystems  found on and surrounding hydrothermal vents and wider deep-sea communities. Much effort has been spent understanding how hydrothermal vent ecosystems are connected to each other but relatively few studies investigate how those communities are connected to […]
