Ocean explorerJon Copleyhas completed dozens of dives to the darkest corner of the rich sea . Yet he is still amazed every time he encounters the foreign life forms that thrive there . Over the past 25 years , Copleyhas traveled to the world ’s deep hydrothermal volcano , to Antarctica ’s arctic " midnight geographical zone " and to spectacular submarine mountain chain across the satellite .
As a professor of sea exploration and science communicating at the University of Southampton in the U.K. , Copley dedicate much of his time to addressing the myriad motion and myth surrounding the deep sea . His new book " Deep Sea : 10 Things You Should Know " ( Orion Publishing , 2023 ) accept a gripping flavor at some of the harsh habitat on Earth .
The deep sea has become a “realm of myth and darkness,” says ocean explorer Jon Copley.
In a video consultation with Live Science , Copley distinguish the late discoveries and where deep sea research is manoeuvre in a warming world .
Sascha Pare : Four year ago , when I was a scholar sit in your deep ocean environmental science lectures , you had just published your first book,“Ask an Ocean Explorer”(Hodder & Stoughton , 2019 ) . That book had 25 chapters , each respond a question that people usually ask you as a deep sea life scientist . What did you set out to do in " Deep Sea : 10 thing You Should Know " ?

We know far more about the deep ocean and its inhabitants than about the moon or Mars, says Jon Copley.
Jon Copley : This new book answer the top 10 questions that I know hoi polloi have about the deep sea and also take on some of the myths and democratic misconception that we sometimes get word . The shorter data format is an opportunity to focus and update the info — there have been quite a few discoveries in lots of dissimilar facet of mysterious ocean biological science since I wrote " need an Ocean Explorer . "
SP : Research has made great pace in late years , I ’m sure . What are some of the most exciting , new discoveries you discuss in the book ?
JC : We’re retrieve out a mountain more about how deep sea animals interact with each other and their environment . An area where we ’ve seen a lot of interesting papers over the past five years has been in sensational ecology — realizing how animals perceive their environment , how they react to that , how they avoid being seen by predators … It was gracious to bring some of those together in a couple of the chapter .
Hydrothermal vents are some of the most vulnerable deep sea habitats and home to 400 animal species not found anywhere else.
SP : Some of the chapters focus on dispelling misconception people might have about what ’s down there in the ocean . What , to your mind , is the biggest , most pervasive myth about the deep sea ?
JC : It ’s the thought that we sleep together almost nothing about it . There ’s this very democratic idea that we know more about the moon or Mars than the thick ocean . That ’s only really true for one very specific aspect of knowledge — have adetailed mapping of the terrain of its square surface — because the moon and Mars are not covered in saltwater , which blocks radar and means we have to utilise asdic in the deep sea . asunder from that , we know far more about the deep sea than those other places .
SP : The thick ocean has attracted a mountain of tending recently in the advent ofdeep sea mining . How worried are you about that ?
The deep sea and the names we give some its features evoke “some kind of underworld,” says Jon Copley.
JC : I guess it ’s great that bass sea excavation has made hoi polloi care more about the bass sea , but it has n’t actually get down yet and inquiry does not support some of the more inflated newspaper headline .
refer : More than 5,000 new species observe in ' pristine ' deep - ocean wilderness . But they could before long be wiped out .
There ’s a draw of enquiry focused on how we ’re going to manage excavation , if it does go forward . And there are some habitat types in the bass sea that wedon’tneed to do further research on , because we get laid they are so vulnerable . We know that we would risk species extinction at active hydrothermal vent , for example , because they ’re a tiny habitat globally — just 50 square klick [ 19 square mile ] — with more than 400 animate being species not found in any other home ground type . But I ’m confident that we will see protection for fighting hydrothermal vents , because we scientists have been saying that for years .
SP : Deep sea minelaying is perhaps more manageable in term of its impingement than other human activities . If not mining , what is the biggest human scourge to the deep sea ?
JC : To my idea , it’sclimate change . And it affects the bass ocean in heaps of different slipway . The one that concerns me in particular is deoxygenation — the reduction in oxygen tier — because cryptic ocean creature need atomic number 8 and they get it from the seawater .
Oxygen is carried down by current that form in the glacial regions and sink and spread throughout the mysterious sea . As a result of clime alteration , the ocean is fuck off warm and that means itcan’t carry as much dissolved oxygen . When water is warmer , the metabolic process of things living in the water runs faster and they apply up oxygen more quickly , so that make the job even worse . And thirdly , we fuck that thecurrents carrying O down to the deep sea are weakening , because melting ice sheet are making the water fresher and blocking the formation of dense piss than sinks .
Those currents take hundred to complete their journey , which means the change we have already made are conk out to hold on being felt for centuries . The rich sea is already on track to have 10 % less O overall globally than it did in preindustrial prison term by 2400 . It ’s concentrated to predict what the bash - on effects are go to be , but they are going to be widespread and they are coming .
SP : You give much of your time to communicating deep ocean science with lay audiences . Why is that so important to you ?
JC : I enjoy speak to the great unwashed about the deep sea because it ’s not somewhere we believe about every Clarence Day . We can go out at night and if we count at the sky , we might enquire about what ’s go on up there . But you ca n’t glance into the deep sea in the same room , so it has become a realm of myth and dark . Even the names of thedeepest bits of the deep sea — the abyssal plain and the hadal zona — suggest that kind of underworld . It ’s nice to be capable to shine a light on that for hoi polloi and to highlight how our lives are connect to it .
SP : Speaking of the sky , how does exploring the deep sea inform thesearch for life outside our solar organization ?
JC : Deep sea geographic expedition has shown us that the orbit of conditions under which life can thrive is far greater than we imagined . The idea that chemosynthesis — where life is power by a variety of chemical energy or else of sunlight withphotosynthesis — could sustain whole populations of animal species was impossible , until we discovered hydrothermal vents and other , exchangeable habitats .

Deep sea vents also glow very faintly — too faintly for the human eye to see , but undimmed enough that microbes can utilize it as an vigor source . Again , it expands our feeling of what ’s possible in the cosmos , because you do n’t of necessity have to be that close to a bright star , potentially , to affirm life history .
