HOPE FOR A NEW DECADE 

Looking back at 2019, one of the most enjoyable posts to put together featured an adult sperm whale with a neonate calf. The wonderful photos were obtained last summer during 2 research trips in the deeper water off the south coast of Abaco by the Bahamas Marine Mammal Research Organisation (BMMRO) It seems fitting to greet the new decade with a revised version of my original post. There’s optimism in these images, and more generally in the recovery in some areas of the savagely depleted whale populations of past decades. I’d like to think that a smiling baby whale holds out hope for the 2020s.

These are just some of the BMMRO research team’s images and footage of the baby sperm whale investigating the underwater world it has just been born into. Hopefully it will flourish and live for decades. If it does not, the overwhelmingly likely cause will be mankind, either directly or indirectly.

‘DEEP DIVERS IN DIVERS DEEPS’: CUVIER’S BEAKED WHALES

‘DEEP DIVERS IN DIVERS DEEPS’: CUVIER’S BEAKED WHALES

JOURNEY TO THE WORLD’S MIDNIGHT ZONE

Please join me in a dive down from the sparkling surface of the turquoise sea to the twilight zone at 200 meters. You’ll pass plenty of sea-life on the way: manatees grazing on seagrass just below the surface; reef fish, barracudas, reef sharks, mahi-mahi, maybe an orca at 100 meters. Other familiar creatures that are found even lower include a few reef fish, some shark species and green sea turtles. You are now running out of clear light.

Cuvier's Beaked Whale, Bahamas (BMMRO / Charlotte Dunn)

As you descend from 200 meters the waters become murky, then inky. The variety of inhabitants and their numbers are gradually decreasing. There are eels, some sharks, squid, stranger deep-water creatures. You may be surprised to see familiar bottlenose dolphins, recorded as diving nearly 300 meters. At 332 meters you will equal the deepest point any human being has ever scuba-dived (Ahmed Gabr 2014). There is little light, but you still have a long way to go to reach your goal.

Descending still deeper, species and numbers continue to thin out. Around the world the limits of larger recognisable species is being reached – more shark species, tuna, chinook salmon, emperor penguins, swordfish, the few corals that can survive the depth. As the light fades to black, giant creatures and strange fish abound. Huge crabs. Sunfish. The (no-longer-extinct) Coelocanth. Massive octopuses. 

Cuvier's Beaked Whale, Bahamas (BMMRO / Charlotte Dunn)

Deeper down, nearing 1000 meters now, there are still some familiar species. Leatherback turtles; Baird’s beaked whales (nb not in the Atlantic); and at 920 meters, the deepest recorded sperm whale dive. It’s pitch dark: you have reached the level that sunlight never penetrates. You are in the Midnight Zone.

DEEP OCEAN DWELLERS

In black depths below 1000 meters, creatures have adpated to create their own light sources – so-called bioluminescence. This is the realm of the self-lit anglerfish, the blobfish and the goblin shark. It’s the Attenborough world of deep sea exploration. The geology is changing: there are hypervents, volcanic rocks, heavy metals. Below are the deep ocean-floor trenches. Yet there are still recognisable species down here, diving astonishingly deep to 1800 meters to feed – not least the narwhal which makes this trip several times a day to feed.

We need to quicken up the descent now – we have to get down nearly twice as far as this to reach our destination…

Cuvier's Beaked Whale leap (M.Rosso GIMA - IUCN)

We pass large squid and isopods, the deepest diving shark – the Greenland, the 10 meter-long 700 kilo colossal squid – yet amazingly there are marine mammals yet to be encountered: at 2400 meters we drift past a huge elephant seal. There are evil-looking creatures down here with names to match – devilfish, viperfish, black swallowers that can eat a larger fish whole, vampire squid and zombie worms. 

At 3000 feet, we finally end our quest. We have reached the depth to which the world’s deepest diving mammal has been recorded: the Cuvier’s beaked whale Ziphius cavirostris


Cuvier's Beaked Whale (NOAA Fisheries)

Cuvier’s beaked whales, or “goose-beaked whales,” are not rare. For a start, unlike many beaked whale species, they inhabit most oceans and seas in the world and have the most extensive range. Unsurprisingly therefore, they are one of the most often sighted beaked whale species and one of the best studied.

FIN FACT

You may be wondering about the pressure exerted on a creature at a depth of 3000 meters. The answer is, an astounding 300 atm (atmospheres), enough to crush all but the hardiest and best adapted of species. The question how these whales manage to survive at such a depth is one for the future…

The Cuvier’s is one of the 3 beaked whale species found in Bahamas waters. Like the rarer Blainville’s and Gervais’s beaked whales, the Cuvier’s is the subject of ongoing research by the BAHAMAS MARINE MAMMAL RESEARCH ORGANISATION BMMRO

The research into marine mammal populations in the Bahamas and far beyond is focussed on the massive increase in single and mass strandings, including recently in a remote area of Scotland (Hebrides) where more than 40 Cuvier’s were washed ashore.

One significant area of research examines the effect on marine mammals of man-made noise. There is plenty of it in the world’s oceans caused by noise pollution in and around shipping channels that traverse marine mammal migration, feeding and breeding grounds; naval surface and submarine exercises; seismic surveys, sonar waves and undersea resource investigations. The evidence of sound / acoustic damage as an additional hazard for marine mammals is starting to look very clear.

SOME NICE PICS OF BAHAMAS WILDLIFE…

WHILE TECHIES LABOUR

Western Spindalis, Abaco Bahamas (Keith Salvesen)

I’m never quite sure how far it’s permissible to go beyond ‘really pissed off’ about a tech problem. Anything much stronger seems a bit indulgent both in itself and especially when measured against the far-reaching despair experienced by many in far more important areas of life.

Northern Parula Warbler, Abaco Bahamas (Bruce Hallett)

I am just having a huge “Grrrrrrrrr” moment because my complex blog menu, with 3 rows of headings and carefully curated nests of drop-downs under each, has been scrubbed by persons or AI unknown. It’s several years of cumulative and (mostly) pleasurable organisational work up the spout.

As a Brit, may I be permitted to say ‘bother’. Or maybe ‘Dash it all?’ Or declare that I’m a mite cheesed orf? To which a fair response would be “it’s just a trivial inconvenience, get over it…”

Abaco Parrot (Craig Nash)

For the moment, here are some nice pics to enjoy, all taken on Abaco. I’m happy to say that right now, 7 weeks since Dorian, there are promising signs that in some areas of Abaco, the birds are starting to show themselves – including a few winter warblers. See you the other side of rethinking my Menu…

BABY SPERM WHALE IN BAHAMAS WATERS: AMAZING FOOTAGE

BABY SPERM WHALE IN BAHAMAS WATERS: AMAZING FOOTAGE

Over several years I have had the privilege of being able to feature wonderful photographs and video footage in this blog. Birds, course, and also reef fish, sharks, seahorses, coral and anemones and a whole lot more. I have also been involved throughout with the wonderful work of the Bahamas Marine Mammal Research Organisation (BMMRO), and have been a part of team since 2017. Abaco is lucky enough to have the HQ at Sandy Point, but we must keep in mind that the organisation’s remit extends throughout the entire Bahamas archipelago, and has firm links with research and conservation organisations on the other islands.

The clear turquoise waters around the islands and their cays are well-known to, and appreciated by, all. This is the playground of the smaller marine mammals – the dolphins, smaller whales and the (now a significant presence) manatees.

   

Less well known are the denizens of the deeper waters and the immense depths of the GREAT BAHAMA CANYON of the northern Bahamas. This is the realm of the large marine animals, from the mysterious speciality beaked whales right up to massive sperm whales.

About 3 weeks ago, the BMMRO research team encountered something truly wondrous off the south Abaco coastline – something to quicken the pulse and gladden the heart – a newborn sperm whale investigating the underwater world it has just been born into. Hopefully it will flourish and live for decades. The hope is sadly tempered by the overwhelming – and increasing – evidence of the terrible effect that humans have caused in just one generation by the pollution of air, land and sea. 

Charlotte Dunn posted the footage of 2 separate sightings. Her first caption reads:

“Close encounter with a curious newborn (‘neonate’) sperm whale yesterday – reminding us of the importance of our Shared Waters project about the effects of ship traffic on resident sperm whales, http://www.bahamaswhales.org/research.aspx. The young individuals like this one will be the most impacted if we don’t make serious conservation changes. As this young whale matures, the policy changes we make in the Bahamas now will affect its survival”.

“While their mothers are feeding at depth (knocking sound in the background) this newborn is being cared for by a slightly older calf until the adults return.”

After the second encounter, Charlotte wrote: “Here’s another amazing short clip of the neonate sperm whale we videoed off south Abaco two weeks ago – thank you to the BEP Foundation and the Devereux Ocean Foundation for funding some of our important work with sperm whales in the Bahamas”.

On Charlotte’s conservation points above, over the last 3 months or so I have been checking daily for posts and articles specifically related to stranded, dead, and killed whales, and their stomach contents as revealed by necropsies. I have collected images from around the world. I won’t wreck this marvellous find in Abaco waters by including any of these. This casual research reveals a horrifying attrition rate for marine mammals. Most animals were full of plastics, from micro through flip-flops all the way up to very large chunks. Some of this junk clearly was the actual cause of death rather than a contributing factor. A whale may take several weeks to die in this way. All of it is entirely the responsibility of mankind – and pretty much caused in the last 50 years.

So let’s enjoy this little sperm whale, and hope it grows to an adulthood that will have seen a radical change for the better in its birth environment – the one that should never have been considered ours to destroy.

SPERM WHALES TAILING: ABACO, BAHAMAS

SPERM WHALES TAILING: ABACO, BAHAMAS

There can be very few people in the world whose breath would not be taken away by the sight of a massive sperm whale tailing close by. And as it happens, this very phenomenon can be seen in the deeper waters around the coast of Abaco. Here is a small gallery of photos of sperm whales tailing, taken from the BMMRO research vessel. There’s no point in my writing a lot of commentary to the images – they speak for themselves of the awesome (in its correct sense) power and grace of these huge mammals.

In these images, you will notice that the whales have distinctive patterns of notches and tears in their flukes (ie tail fins). As with a dolphin’s dorsal fin, these areas of damage are like fingerprints – unique to each individual, and a sure means to identification. The researchers log each sighting and assign a cypher – a whale will become known as ‘B42’ and not usually by a less scientific name like ‘Derek’ or ‘Susie’).

Q. What happened next?  A. You would see the tail emerge as the whale dives deep… Sperm Whale Tailing, Abaco, Bahamas (©BMMRO)

One of my favourite whale views is of the tail as it rises above the surface with water streaming off the flukes, before it flicks over and disappears beneath the waves.

‘WELL SPOTTED’ (2): ATLANTIC SPOTTED DOLPHINS IN ABACO

No sooner have I posted about PANTROPICAL SPOTTED DOLPHINS sighted during the current BMMRO whale research program, than the other Bahamas spotted dolphin species shows up as well. These are the more numerous Atlantic Spotteds Stenella frontalis, more confined in range (as the names suggest) than the Pantropicals.

The BMMRO caption reads “Atlantic spotted dolphins today! Small social group playing with sargassum – they swam past what looked like a plastic mattress cover – one dolphin whacked it with its tail as it swam by…”

RUBBISHING RUBBISH: A RANT

Behold a large plastic bag, made by humans and dumped by humans into a place that is not theirs to use as a trash repository. It will take some 500 years to break down completely. But when people say that they don’t really mean it will have harmlessly disappeared over that period and become salt water. Far rom it. It will just break down into smaller and smaller pieces, to bite-sized bits for turtle, fish and seabirds who will idiotically mistake them for food (duh!), then to micro-plastic that will become part of the evolving plastic soup that will be ingested by tiny sea creatures and coat the reefs in polyethylene gunk. [End of rant. Ed.]

Behold an Atlantic Spotted Dolphin giving the bag a passing whack with its tail. It won’t do anything to help with marine pollution, but is shows a robust disdain for a piece of man-made rubbish that has made it into the creature’s home environment.

Below is a short GoPro shoot of a pair of ASDs, that I took from the BMMRO research boat last year. Marvel at the grace and elegance of these beautiful animals as they swim just below the surface (wonder, too, at the incompetence of the cameraperson who, to be fair, was leaning over the side of the RHIB with the camera on a stick…)

SPERM WHALES GATHERING IN ABACO WATERS


Sperm Whales, Abaco Bahamas (BMMRO / Keith Salvesen)

SPERM WHALES GATHERING IN ABACO WATERS

During the past week, the BMMRO research boat has been tracking sperm whales off the south coast of Abaco. These huge creatures are the largest marine mammals found in Bahamian waters, and the area between Rocky Point around the south coast to Hole-in-the Wall is a great place to find them. 

Sperm Whales, Abaco Bahamas (BMMRO / Keith Salvesen)Sperm Whales, Abaco Bahamas (BMMRO / Keith Salvesen)

One reason they are found in this particular area is the existence of the Great Bahama Canyon, one of the deepest submarine canyons in the world. The depth of the canyon ensures that the waters are nutrient-rich, with food being drawn up from the depths towards the surface. In season it’s the perfect place for female sperm whales and their calves.

The BMMRO research trip encountered more than a dozen sperm whales, mostly females with their calves. And the amazing thing is that the sightings are often made within sight of land. In these photos, the are two landmarks visible. One is the huge Disney vessel parked at Gorda Cay aka Castaway Cay (header image); the other is HOLE-IN-THE-WALL LIGHTHOUSE (above)
