Written By Dr. Steven Katona, Managing Director, Ocean Health Index. What do you think an IQ score actually tells about a person, besides it being less than 70 which means you could be mentally retarded? J. McCarthy (2010). We’ll begin with marine systems where poop is a welcome source of nutrients and food. During the last century population growth far outstripped effective treatment of wastes. The Gulf of Maine and Antarctic studies suggest that fertilization of primary production by the whale pump or by recycling iron was even more important before hunting decreased whale populations and before industrial-age air pollution delivered large amounts of atmospheric nitrogen. However, it still contains all the nutrients that people excreted, including the nitrogen, phosphorus, iron and other elements that plants use. The significance of  discovery of fossil species “Tiktaalik” to understand the history of evolution the lineage that gave rise to humans? What is the biggest waste of human potential? That means the average ocean "fish tank" is about 65 Olympic swimming pools (there is about 2500m 3 in an Olympic sized swimming pool) Now if we change the initial assumption of the average fish mass = 0.25 kg to say a more conservative 0.05 kg, the average ocean "fish tank" is 32500 m 3 or about 13 Olympic sized swimming pools . Whales feed at deeper levels of the ocean where krill is found. New England Aquarium researcher Dr. Rosalind Roland with Fargo pointing the way toward right whale poop. Treatment plants must be designed to accommodate such large volumes.What comes out of the sewage system may be untreated (raw) sewage; sewage with big pieces screened or settled out and fat skimmed away (‘primary treatment’); screened and de-fatted sewage that has been digested by bacteria and other microbes (‘secondary treatment’); or screened, settled, digested sewage that has been further treated to remove nitrogen and/or phosphorus (‘tertiary treatment’). J. McCarthy (2010). Dotted light lines = 95% credible intervals around the estimate. Only very strong storm winds can stir the cool, dense, nutrient-rich water up into the warmer surface layer. Effluent from secondary-treated sewage is almost always partially disinfected using chlorine, ozone or ultraviolet light to kill most microbes, though viruses may survive. These kinds of things can alter the water/gas content of your feces, which in turn defines its density. Otters also have particularly stinky poop, which even has its own name: spraints. if its more dense than seawater then it will sink, it might be spongy or extremely solid so it will depend on your poo, i think the sea water density would depend on what ocean or sea you were talking about, ALSO thought the density of WATER is 1g/ml, sea water is more dense so if your poo floats in water then it will prbably float in the ocean. You need more gut bacteria to break them down. Of course people pee too, an average of 1 to 2 liters per day (we’ll say 1.5 l), so that adds nearly 11 billion more liters of fluids excreted to the environment (see other estimates here). Sperm whales and beaked whales may dive a mile or more to hunt squids and fish. The floating stool may appear to be oily or have oil around it. Actual whale poop floats though with a fatty substance called ambergris, a rare substance that has been highly valued for thousands of years as an ingredient in perfume and pharmaceuticals. Among other fecal-borne diseases are gastroenteritis, typhoid, paratyphoid, salmonella, cholera, meningitis, hepatitis, encephalitis, dysentery, amoebic dysentery, giardia and parasites such as roundworms. How do you think about the answers? That system, completed in 1884, collected sewage from 18 cities and towns, piped it to Moon Island in Boston Harbor for released on every outgoing tide! For most of human history our communities were so small that poop was mainly a nuisance, at times spreading disease or parasites locally, but also providing a benefit as a fertilizer for crops. Poop that is denser than water will sink, whereas poop that is less dense than water will float. Distribution is very uneven, with 99% of people in the developed world having improved sanitation compared to only 52% in developing regions. Before we dive into poop odor, let’s talk about your poop’s appearance, which can provide clues into the state of your health. Photo: Brenna Kraus, Aug. 19, 2005, Bay of Fundy, courtesy of, Population of southern hemisphere blue whales, 1900-2000. 1 in Global Environmental Marine explorer William Beebe saw the particles from the window of the Bathysphere during his first dive off Bermuda in 1930 and described them as ‘marine snow’. If your poop never seems to sink in the toilet bowl, that can be a reflection of your diet and certain health conditions. About 90% of sewage is water, since sewer pipes also includes the water from baths, showers, dishwashing, toilet flushing and many business and industrial uses. the bottom of each email. No, because sea cucumbers poop that waste out again. Normally millions of gallons per day of secondary-treated waste water (see below) are discharged into the harbor. if its dense enough itll sink it might float cuz its in salt water which has higher density than normal water, another possiblity is that the salt water will break down the "poop" and disapated it into a liquid...turning the water around u a disguisting color and everyone on the beach points. If the water is not too deep, some fecal pellets reach the bottom nearly intact, where worms, sea cucumbers and other bottom dwellers probably eat those with highest content of carbon and nitrogen. Other causes of floating feces include a high fat content in the stool, which may be a result of chronic pancreatitis. Krill eat the phytoplankton, accumulate iron from the minute plants and store the iron in their bodies, retaining nearly one-quarter of all the iron in the sunlit zone. According to the National Institutes of Health (USA), healthy stools typically sink. Foods containing insoluble fibers, starch, artificial sweeteners are hard to digest. However, the process is usually judged too expensive for most treatment plants. At the same time, the by Dave Stopera. In the ocean, as on land, plants anchor the food web. Is it possible my brother was cloned in the 90s and he was replaced?His behaviour was so different.? The new coronavirus SARS-CoV-2, which has now infected nearly 76,000 people, spreads mostly through respiratory droplets and contact with infected patients. In this case, eating more fatty food than normal is … In the ocean, as on land, plants anchor the food web. Floating stool can also signal a condition called malabsorption, when the body is not processing nutrients properly. Tertiary treatment removes nitrogen by using bacteria that convert ammonia to harmless nitrogen gas; and removes phosphorus either using particular bacteria that bioaccumulate it or by coagulation with aluminum or iron followed by precipitation and filtering. The Whale Pump. Red dots = available absolute population estimates. Credit: Fig. Whale poop may be critically important in another way in Antarctica, where lack of iron in the surface waters limits phytoplankton growth. Tertiary-treatment protects people, because it is disinfected to remove pathogens; and it also protects the environment, because it removes the nutrients that cause eutrophication and excessive algal growth. It helps fertilize the entire pelagic food web. The bacteria are normal residents of the intestinal microbiota that digests food and helps us in many other ways.Using a rough average of 5 ounces of poop per person per day, consisting of about 1.25 ounces of solid matter and 3.75 ounces of water, the daily global load is 284,871 tons (258,431 metric tonnes) of solids and 854,613 quarts (808,766 liters) of liquid. An infection in the gastrointestinal tract, such as from E. coli, Salmonella, or … Rather the fluffy plume floats at the surface. What keeps the system going? 22 in. Improved sanitation reduces the spread of fecal-borne disease both by limiting direct contact with excrement and separating the flow of excrement from drinking water supplies, but it does not necessarily help the environment. You can sign in to vote the answer. In very sparsely settled areas material from diseased individuals may wash into wells, waterholes, lakes, streams or rivers bringing illness to people drinking or contacting the water, but in sparsely settled areas . Human poop isn’t the sole cause of all the problems mentioned above, because sewerage also contains discarded food, wastes from our pets and some industrial wastes. * If there is 1 particle of fecal mater in a 1m³ tank, does it mean that it’s 1 m³ of contaminated water ? When that happens, the combined flow bypasses treatment plants and is to this day released untreated into the harbor from several dozen outlets. The first plant to treat the sewage was built in 1952, but raw sewage was released until 1997, and dumping of sewage sludge into Boston Harbor only ceased in 1995. billion and is expected to reach 9 billion by 2050. FYI: People Poop In The Ocean, So You Gotta Worry About That Too "It was a floater." The most common reason you're stool floats is that it contains a lot of gas. ? Joe Roman and James McCarthy named this process the ‘whale pump.’, Illustration credit: Figure 1 from Joe Roman  and James B. Christensen and Daniel Pauly. Pigs, dogs and other scavengers may eat it and flies attend to the rest. When a whale releases its excrement the whales poop comes out as an almost liquid form of fecal matter (often in a plume-like cloud) and is light enough that it does not sink to the bottom sea but floats across the top of the ocean; in some cases the excrement may also come out in chunks rather than a plume-like cloud. The color of the poop is red, thanks to its krill-eating lifestyle. And i was wondering if you were to **** into the ocean, like whille u were in the ocean water's, would it float or would it sink and why? Fragments dislodged or broken by storm waves float, grow, and accumulate into large mats in the Sargasso Sea that host a diverse and unique biological community. More poop entered wells, lakes, streams and rivers, affecting the environment as well as human health. This oceanwide ‘snowfall’ is also called the ‘biological pump’ because it is the primary way food reaches deep water animals and seafloor communities. The currents of the North Pacific gyre collect trash—mostly bits of microscopic plastic—into what are known as "garbage patches." Credit: Fig. The problem is less pressing near shore, where runoff from land brings nutrients from eroded soil, decaying plants and animals and fertilizers used in agriculture as well as discharge from sewers and sewage treatment plants (more on this later). And if your poop contains more air or gas than normal, it will make it lighter—thus more likely to float on top of the water than sink to the bottom of it, like denser turds do. When the plants die, bacteria decompose them, often using up the water’s dissolved oxygen and creating a ‘dead zone’ where aerobic marine life cannot survive. Floating on the ocean surface, the plastic litter may get caught in one of the many wind-driven ocean currents and then make its way to the center of an ocean gyre—a massive circling ocean current. Marine mammal populations: reconstructing historical abundances at the global scale. population growth far outstripped effective treatment of wastes. Does it mean your good eating habits are lost at sea? Here’s what the experts say. It helps fertilize the entire pelagic food web. The poop, which could sometimes be in liquid form, is often seen floating on the water surface and does have a strong smell. “exploded” in the past 1 000 years. It will depend on what you ate, how long it was retained in your colon, etc. As communities grew, so did filth, odor and disease. Floating poop can be caused by: Poor absorption of nutrients — called malabsorption; Too much gas, which can occur with a change in your diet; human population has skyrocketed from 1.6 billion in 1900 to more than 7 Both found the same thing. Shared facilities are not counted as ‘improved’ in World Health Organization-UNICEF data.Finally, the 64% with access to “improved” sanitation have a flush toilet with a piped sewer system, septic tank, use a pour flush toilet, pit latrine, ventilated improved pit latrine, pit latrine with slab or a composting toilet. Honestly, this is a SERIOUS QUESTION. Red dots = available absolute population estimates. It feeds deep down the ocean and swims to the surface to relieve itself. Furthermore, runoff of fertilizers and soil from agricultural fields and runoff from livestock feedlots where cattle and pigs are raised at high density join the effluent from numerous cities along river courses, contributing to dead zones where many rivers meet the sea. The excessive nutrients foster large populations of ‘weed’ species of algae and phytoplankton that reduce water quality, clog fishermen’s nets, harm fisheries and  mariculture and help cause toxic red tides. Stomach infection. Photo: Brenna Kraus, Aug. 19, 2005, Bay of Fundy, courtesy of  New England Aquarium. Floating Poop. Whales and other deep divers, such as elephant seals and Weddell seals deliver nutrients to the plants by feeding at depth, but frequently pooping near the surface. For the most part, if it floats, doesn't smell bad and it brown, you are probably OK. Individuals make different amounts depending on their sex, body size, diets, frequency of bowel movements, states of health and other factors. Everything in the Antarctic eats krill and whales are the major consumers. And if your poop contains more air or gas than normal, it will make it lighter – thus more likely to float on top of the water than sink to the bottom of it, like denser turds do. This happens when you eat foods that make you fart a lot. Many things must be done to maintain human health and restore ocean health, but for coastal waters, solving the human poop problem is one of the most important. Whale poop may be critically important in another way in Antarctica, roughly 10 million times the concentration of iron as in the surrounding water.
