In The Field

The matts of Sargassum washing up in Bermuda lately have been the largest and most sustained in recent memory. This has created problems in some cases and opportunities in others (especially for photography and filming). Please stay tuned for many more posts once we take a break from filming.

For World Oceans Day another photo from the series showcasing the importance of Sargassum and the Sargasso Sea as a nursery.


This one has a thumbnail sized juvenile Sargasso fish that sat there, eating the Flying fish fry as they hatched, even as we were filming.

A White-tailed Tropicbird known in Bermuda as a "Longtail" has just returned from foraging in the Sargasso Sea and feeds a squid to its 1 week old chick in its nest on the Nonsuch Island Nature Reserve in Bermuda.


This clip was extracted from the 24/7 LIVE Streaming "Tropicbird Cam" a collaboration between the Nonsuch Expeditions, the Cornell Lab of Ornithology and the Bermuda Governments Department of the Environment and Natural Resources.

The latest waves of Sargassum that have reached Bermuda have been full of fauna early in their life-cycles as documented by Nonsuch Expeditions Team Leader and Sargasso Sea Commission Ambassador Jean-Pierre Rouja in a series of photos.


In this photo is a gravid Sargassum Swimming Crab (of which there were numerous in our latest collection efforts) holding her eggs, along with strands of Flying Fish eggs that had been wrapped around the Sargasso weed (Sargassum natans) and were just about to hatch.

Whilst out on assignment, we collected fresh samples of Sargassum which contained a fair amount of fauna early on in their life cycles including some very small Sargassum Fish, clutches of Flying Fish roe and this gravid Sargassum Swimming Crab itself carrying eggs, which can be seen in this photo.

The recent batches of sargassum reaching Bermuda contained a variety of fauna. As usual the variety of species and stages of their life cycles is affected by the time of year and other lesser known factors.


For example this week when collecting just south of Nonsuch Island, despite several hours of searching through patches of sargassum which was in relatively good condition, we primarily observed an abundance of shrimp, but very few crabs, and we only found 3 very small sargasso fish ranging from 8mm to 20mm.

We also found 3 very small, thumbnail sized octopus, which we do not see very often.

This is perfect timing for the Sargasso Sea Commission meetings taking place in Bermuda this week who we plan to take out on an Expedition including Nonsuch Island to meet the newly hatched Cahow chicks.

Sargassum, after which the Sargasso Sea is named, is found in Bermuda's waters sporadically at different times of the year, so when it arrives we must make the most of the opportunity to study and document it.

Expedition Background

We have been involved in multiple Expeditions documenting Sargassum Biodiversity including working with National Geographic, BBC Blue Planet / Natural History Unit and Silverback Films.


The challenge in all these cases is observing the habitat in its natural state prior to our boats or divers approaching and disturbing it, which invariably scares many of our larger Pelagic subjects away.

The plan is to use remote drop cameras along with a Trident and aerial drones as remote observation platforms, allowing us to observe and document a wider range of fauna.

Expedition Team Leader J-P Rouja is an Ambassador to the Sargasso Sea Commission and will use this Expedition for educational and public outreach.
