Into the DeepJuly 16 2018
The Deep Ocean Dropcam, developed by the National Geographic Society Exploration Technology Lab, is a robust and efficient platform for exploring the deep ocean. In order to assess global deep ocean ecosystem health and identify areas in need of protection, we will develop key indicators with metrics such as taxon richness, abundance, and community diversity in the deep ocean. By coupling biological metrics with environmental variables such as depth and habitat, these measures will establish the first global baseline to serve as a standard against which to measure any change in the deep sea.

I am now embarking on compiling the first chapter of our global deep ocean ecosystem health assessment, which will be a look at species community composition and biodiversity in the Eastern Pacific Ocean.
Now I am viewing video footage captured from Malpelo Island, in the Pacific Island off of Columbia. Pristine Seas made an expedition there earlier this year: https://www.nationalgeographic.org/expeditions/malpelo/
As I view the deep sea Dropcam footage to ID species and count their numbers, I also like to stop and draw some of the creatures because with drawing I access a much deeper window into the species biology and ecology. It allows me to spend more time with the creatures encountered, and come up with new questions about them. It takes more time, but I find it to be a really fruitful method of inquiry, as well.
This picture is of an uncommon shark, though is seen frequently on the deployments at Malpelo. Its species name is Echinorhinus cookie (or Prickly shark) and it is found to ~1,100 meters depth in the Pacific Ocean. Its body is covered in an armor of thorn-like, teeth known as ‘denticles’ (hence the “Prickly” common name). This shark gets to be quite large (up to 400 cm). It feeds on a variety of fishes, other sharks, octopi and squids.
It is classified as Near Threatened by IUCN. It appears to be vulnerable to deepwater trawling and line fishing. With increased fishing activities, this may negatively impact their already small and fragmented populations. Being large and slow-growing, they have limited ability to recover from disturbances.
As I drew this picture, I thought about the negative space, the surrounding watery environment under such great pressures - what does it feel like to move through water at 1,000m depth? I too would want those large fins, and to be covered in teeth for armor!

The earth’s surface is mostly covered by ocean. How do we even begin to prioritize where to drop cameras to view what lies beneath the surface? Because of the pioneering work of National Geographic’s Pristine Seas, we already have a global foundation to build upon, to begin constructing the index of deep ocean ecosystem health. Dr. Enric Sala and his team have collected video footage from many remote and amazing places across the world’s ocean. This map shows some of the sites with existing video footage that we can synthesize to jump-start the global assessment (follow the Pristine Seas missions here, on Open Explorer!). Going forward, our team will be building platforms to organize the data, viewing and annotating the video footage, identifying sea creatures and counting their abundances, analyzing the data for patterns in biodiversity, and strategizing where to drop the cameras next!
To explore the deep ocean we need innovative technologies and new solutions to let us see even further into the deep sea, and to shine a light there. The Deep Ocean Dropcam, developed by National Geographic Exploration Technology Lab, as an efficient way to capture video of the sea floor. It is a high definition camera encased in a pressure housing rated to go to the deepest part of the ocean, with onboard lights to illuminate the scene. The camera is weighted and free falls to the sea floor, where it is programmed to record for a number of hours. When it is done recording, the burnwire connecting it to the weight dissolves, and it freely floats to the surface for recovery by the ship. Check out the video here on the camera’s drop and recovery with awesome engineer Brad Henning!
The deep sea is the least explored and the least understood part of our planet. In this vast and extreme environment, even less is known about the biological communities that exist there, or the biogeography of deep ocean species. Out of sight and out of mind, these fragile ecosystems are silently at risk of extinction from climate and anthropogenic pressures in this time of rapid global change. To attain a planet in balance and sustainable futures, it is evermore imperative to expand human understanding to the deep sea. This project is designed to transform innovative exploration technology (the Deep Ocean Dropcam) into an active research program to protect biodiversity in the deep sea. We will establish a baseline deep ocean health assessment to identify areas for the protection of biodiversity and monitor ecosystem health into the future. With the expansion of the Dropcam program, we have the opportunity to bring the deep sea into sight and into mind.
