I first encountered whale poop 30 years in the past whereas I used to be engaged on a proper whale analysis mission. On one among my first days on the water, within the Bay of Fundy, in jap Canada, we stumbled on a feeding male proper whale with mud on its head – or bonnet – an indication that it had been feeding on the backside of the bay. It had come as much as breathe and relaxation.
Simply earlier than it dived in once more, it launched this monumental faecal plume.
There have been gallons of poop in that water. It seemed like crimson floating bricks. The odor was overwhelming. Some whale poop smells like brine and seawater, however with proper whales, there’s a powerful odor of sulphur.
In case you get that poop in your garments, it’s a must to throw them away. You’re by no means going to scrub it out.
I didn’t comprehend it then, however that faecal plume would later spark my international seek for whale faeces, from Iceland to Mexico, Alaska and Hawaii.
Since then, I’ve realized that whale faeces can inform us not solely in regards to the weight-reduction plan of a whale, but in addition about their hormones and reproductive standing. It may possibly reveal the whale’s stress ranges, intestine microbiome and genetic lineage. It even permits us to take a look at the extent of mercury and air pollution within the ocean – all the things from microplastics to parasite masses.
Ambergris, which is shaped within the hindgut of sperm whales once they digest squid beaks, is uncommon and intensely invaluable. For the reason that Seventies, its commerce has been restricted in lots of international locations. However up to now, it was used to make perfumes, which had been worn by Elizabeth I, Charles I and Casanova.
Whale faecal plumes may be neon inexperienced or vivid crimson. At occasions, they sparkle with silver scales, just like the solar glinting on the water. Each whale defecation is exclusive.
As for the odor, the poop of proper whales is the strongest and foulest however I really like the odor now.
It helped set the course for my analysis profession. Two years after I noticed whale poop for the primary time, I took my first-class in marine ecology and realized about some of the necessary processes within the ocean, particularly in carbon sequestration: the organic pump.
Phytoplankton, or algae, solely develop close to the floor of the ocean, the place there’s sufficient mild for photosynthesis. Animals reminiscent of krill and copepods feed on it there and they’re eaten by fish and even whales.
When this phytoplankton dies or is consumed, a few of these vitamins are faraway from the environment and may sink to the underside of the ocean. On this means, the organic pump performs an necessary function in transferring carbon to the deep sea.
However I bear in mind sitting there at school that day, considering: there’s one thing lacking right here. Proper whales usually feed at depth and poop on the floor, in order that they’re probably bringing necessary vitamins like nitrogen, phosphorus and iron again as much as the floor.
That set me off on the concept of a “whale pump” – which we’ve since found does the other of the organic pump. It pumps vitamins again as much as the floor.
These vitamins can get picked up by phytoplankton and undergo the complete ocean meals chain. That is necessary as a result of one of many justifications for whaling in Japan, Norway and Iceland is that whales eat “our fish”, subsequently if there are too many whales, there can be a decline in fisheries.
The whale pump demonstrates it’s extra sophisticated than that – and that the presence of whales within the ocean would possibly really improve fish populations.
In addition to serving to us to grasp the state of the current ocean, whale poop provides us a glimpse into the previous ocean and what it was like when there have been lots of of 1000’s of whales within the sea. If we are able to restore whales and the nutrient pathways that traditionally existed by means of their poop, it might assist assist extra biodiversity within the ocean.
