24 June 2015 - New publication: Deepest record of the Scalloped Hammerhead.
This observation of a scalloped hammerhead (Sphyrna lewini) is the deepest accurately reported in the scientific literature. It was made from an ROV launched from the Deepsea Metro 1 at over 1000 m depth off Tanzania in the western Indian Ocean.
21 May 2015 - Article about collaboration with Shell in the Gulf of Mexico
Shell have published an article about collaboration with Prof. Mark Benfield to improve understanding of deep-sea biodiversity in the Gulf of Mexico.
The article is available on Shell's Inside Energy online magazine.
19 November 2014 - New video highlights from the Gulf of Mexico
A new highlights video from Mark Benfield's Gulf SERPENT work is available at http://youtu.be/esNqNzHia7U.
This shows observations of marine life at a range of depths viewed from industrial ROVs in the Gulf of Mexico as part of the Gulf SERPENT Project. Gulf SERPENT is funded by the Bureau of Ocean Energy Management with in-kind funding by Shell, BP, Chevron, and Petrobras-America.
13 October 2014 - New paper on Angolan megafauna
Daniel Jones has published a new paper in Deep Sea Research I about the megafauna associated with asphalt mounds on the deep sea floor off Angola. Asphalt mounds are formed from hydrocarbon seepage associated with subsurface salt structures. The paper describes mapping 2254 asphalt mounds and then using industry ROVs to explore them in further detail. The mounds provided habitat for many epifaunal species and these structures may represent important habitat on other continental margins around the world.
The paper is Open Access and available for download from the journal Deep Sea Research Part I.
20 May 2014 - EU Maritime Day
Andrew Gates presented SERPENT at EU Maritime Day 2014 in Bremen in the stakeholder workshop entitled "Sustainable extraction of marine resources from the deep sea". The presentation, invited by OGP, showed how collaboration between scientists with industry can be used to increase our understanding of the deep sea. It was also an opportunity, during a panel discussion about extraction of resources, to show video of the often fragile organisms and habitats of the deep sea as a reminder of the importance of monitoring and limiting impacts in unexplored areas.
16 May 2014 - Natural history meets data mining
An article on Echinoblog shows how observations collected through a variety of deep-sea research projects can be collated to inform our understanding of the ecology of animals we would otherwise have limited access to study. Among other observations the article highlights images from the SERPENT archive that show the asteroid Porania pulvillus feeding.
The SERPENT images were collected at the Lancaster and Whirlwind sites west of Shetland through our collaboration with Hurricane Energy, the Cashel site off Ireland in collaboration with Statoil and at BP's Schiehallion location. Details of the SEPRENT visits are available on the Missions pages.
13 May 2014 - Food falls off Angola
Working with Nick Higgs from Plymouth University, SERPENT scientists Daniel Jones and Andrew Gates have published a paper describing some amazing observations of the carcasses of a whale shark and mobulid rays at the seabed 1200 m deep off Angola. This research represents the first observations of large food-falls aside from whale-falls. The paper describes the scavenging fauna that feed at this bonanza of food and considers the role of large food-falls in the export of carbon to the deep sea floor.

30 January 2014 - Article about SERPENT work off Tanzania
BG Group have published an article about recent SERPENT Project visits to the Deepsea Metro 1 drillship operating offshore Tanzania. This is part of an ongoing study of the deep sea in an unexplored part of the Indian Ocean off East Africa.
21 June 2013 - SERPENT Nigeria paper published
Our paper describing the deep-sea life recorded off Nigeria has just come out. This paper details the results from our work with Total Nigeria at the Usan (and Akpo) sites on the Nigerian Margin. This work documents the changes in the seabed life in relation to seabed slope just outside the main hydrocarbon development area at Usan. It is the first study to look at the larger seabed fauna in the deep-waters of Nigeria. We found some important insights into the role of seabed slope (or factors associated with it) in structuring communities, as well as documenting some impressive and diverse assemblages of deep-water fauna, particularly in areas of high slope. The paper can be downloaded here and is listed on our publications page.
10 June 2013 - SERPENT observations of Oarfish hit the news.
Extraordinary footage of a rarely seen giant deep sea fish has been captured by SERPENT scientists. Using a remotely operated vehicle, Mark Benfield (the leader of GulfSERPENT) caught rare video of five oarfish. These appear to be the first observations from remotey operated vehicles (ROVs) and are among only a few sightings of the fish in its natural oceanic habitat. The oarfish, which can reach 6-8 m in length, is generally known from dead or dying specimens that was ashore.
Oarfish (Regalecus glesne) are one of the world's longest fish reaching 6 - 8 m. Their strange appearance may have provided the basis for the sea serpent myths told by early ocean travellers. Not only are they elongated, they also have a prominent dorsal fin which gives it an unusual "serpent" appearance. Benfield's team reports on the deepest record of an oarfish from 493 m below BP's Thunder Horse platform. Recalling the event Professor Benfield explained how at first, they thought the fish was simply a drilling pipe called a riser being lowered into the water. "We saw this bright vertical shiny thing, I said 'are they lowering more riser?' as it looked like they were lowering a huge pipe." "We zoomed in a little bit and we said 'that's not a riser that's a fish!'". "As we approached it retreated downwards swimming tail first in a vertical orientation as the ROV followed," Professor Benfield explained. The team followed the fish for about five minutes before breaking off contact to resume their surveys. "What was interesting about the fish was its swimming behaviour," said Professor Benfield. "It moved by undulating its dorsal fin in waves that propelled it backwards at quite a good speed." Early estimates measure the fish at between 5.1 - 6.8 m in length.
Professor Benfield said this may be the first time the oarfish has been filmed alive swimming in the so-called mesopelagic layer of the ocean. Usually, they are seen dying at the sea surface or washed up dead. The fish may have been caught on camera at a depth of 765m at another Serpent survey site, off western Africa in 2007, but a positive identification has not yet been made from that video. On this occasion the fish was observed underneath Thunderhorse in the Gulf of Mexico, one of the largest semi-submersible oil rigs in the world. The Serpent project run by the National Oceanography Centre, Southampton (NOCS) is a unique collaborative project between scientists and industry. Oil and gas companies allow scientists access to their deep sea technologies and infrastructure in a bid to aid their research. "(It) provides a wonderful opportunity to learn more about life in the depths of the Gulf of Mexico. That we found an oarfish while doing so was a fantastic bonus," said Professor Benfield. Professor Benfield is excited by the potential for further discoveries and revelations from the deep that the SERPENT project may bring. "It's all very exciting, my vision for the Gulf SERPENT Project is to establish a Gulf-wide deep sea biological observation system, with hundreds of ROV-equipped ships and rigs in the deep Gulf." "(We can) get a good idea of what species are present, where they are present, and what they are doing.".
The results of this study have been published in the Journal of Fish Biology. Links to all five observations are available from: http://onlinelibrary.wiley.com/doi/10.1111/jfb.12144/suppinfo. This story has also been heavily reported in the mainstream media and blogosphere. Including the BBC news, Daily Mail and Deep-sea News.
4 February 2013 - INDEEP settlement frames recovered.
The first frames have been recovered from a collaborative project to investigate larval recruitment in the deep sea using industry infrastructure.

24 January 2013 - Meeting in Tanzania
Andrew Gates went to Dar-es-Salaam to present the results of SERPENT's field work off Tanzania. Statoil organised the seminar to present and discuss environmental projects related to their deep-water exploration. As part of this work, Andrew went offshore from Tanzania last year to investigate deep-sea biodiversity around drilling rigs operating in the area. A mission report will be on the SERPENT website soon.
Images collected offshore Tanzania are archived in the SERPENT database.
19 December 2012 - Daniel Jones' guest post on Deep-Sea News
Read Daniel Jones' guest post about SERPENT's recent work on deep-sea hydrocarbon drilling on the Deep-Sea News blog.
17 December 2012 - SERPENT at the 13th Deep-Sea Biology Symposium in Wellington
Andrew Gates, Daniel Jones and Charlie Main recently attended the 13th Deep-Sea Biology Symposium in Wellington, New Zealand.
Andrew presented the results of recent SERPENT research on disturbance and recovery from hydrocarbon drilling in deep water and Charlie described the results from her experiments investigating the effects of oil on deep-sea sediments. Daniel's presntation predicted the effects of climate change on future benthic biomass.
The presentation titles were as follows:
Gates; The SERPENT Project: Exploring deep-sea life, anthropogenic disturbance and recovery at hydrocarbon exploration sites
Main; Investigating the effects of deep-sea oil spills on sediment community oxygen consumption
Jones; Future reductions in global ocean benthic biomass predicted as a result of climate change
20 November 2012 - SERPENT studies on recovery from disturbance in deep water are available online
The two studies of disturbance in deep water which SERPENT scientists have been working on have now been published. The study from the Laggan site in the Faroe-Shetland Channel is published in Marine Ecology Progress Series and the study from Morvin in the Norwegian Sea is in PLOS One. The studies were carried out at 600 m and 380 m depth.
The work suggests some evidence for recovery after three years at both sites but confirms that full recovery in the deep sea may take many years.
Both papers are open access so they are freely available to download:

15 October 2012 - Deep-sea biodiveristy in the Eastern Mediterranean - SERPENT's deepest site
A study has been published recently describing the results of SERPENT work carried out onboard the Discoverer Americas in the Eastern Mediterranean. At 2720 m this is SERPENT's deepest study site so far.
The paper in African Journal of Marine Science describes the benthic megafauna and fishes observed during a week of ROV observations at the Kiwi location north of Egypt. This part of the Mediterranean is extremely oligotrophic owing to high water temperature throughout the water column (14C at the seabed) and megafaunal abundance was very low. Occasional observations of crabs and fish were made but it was not until bait was deployed that any numbers of organisms were recorded. Even then it was predominantly one species of crab.
The paper is available here:
