Researchers over in the Northeast have just poured 65,000 liters of sodium hydroxide
0:06
into the Gulf of Maine in order to conduct a geoengineering project which they claim at least
0:11
might combat climate change. This trial, which is officially called the Loch Ness Project,
0:16
it took place last August about 50 miles off the coast of Massachusetts. That was when scientists
0:22
from the Woods Hole Oceanographic Institution were seeing pouring literally tons of this bright
0:28
red chemical directly into the water over the course of roughly four days. The thinking is that
0:34
by making the ocean more alkaline, it'll suck more CO2 from the atmosphere and turn it into
0:40
harmless baking soda. The addition of the red color, it was just there for tracking purposes.
0:46
Now, this is something that the ocean does already do naturally. It's estimated in fact that the
0:52
five oceans trap a combined total of 38 trillion tons of CO2, but that's their natural limit based
0:59
on the current average pH level of the water. The oceans literally cannot absorb any more CO2
1:05
at least naturally. However, this is exactly where the scientists come in. The thinking is,
1:10
by changing the pH level of the ocean using sodium hydroxide, they can get the ocean to absorb ever
1:16
more CO2. The geoengineering method known as ocean alkalinity enhancement aims to speed up
1:23
this natural process by resetting the ocean's pH. Over four days, scientists added vast quantities
1:28
of sodium hydroxide, an alkaline chemical tag with a red dye to the waters off the coast of Boston,
1:34
making the ocean more alkaline should encourage it to absorb even more CO2 from the atmosphere.
1:39
Now, over on their official website, you can see that the Woods Hole Oceanographic Institute
1:44
actually has a graphic showing this idea as a simple drawing. Essentially, in the past,
1:50
they claimed that the oceans were a lot more basic. However, with the addition of ever more CO2
1:56
from the atmosphere, the oceans began a process of absorbing the carbon dioxide from the air
2:02
and becoming more and more acidic over time. However, through their alkalinity enhancement procedure,
2:07
they can add sodium hydroxide to the ocean water, which will at least in theory lower the pH
2:14
level while at the same time allowing ever more CO2 to be captured. And so that's the basic
2:19
theory that they had going in. This institute then got approval from the EPA and conducted a test
2:26
by pouring this chemical solution into the ocean roughly 50 miles off the coast of Massachusetts.
2:32
During this test, they poured in enough of this chemical solution to change the pH of the water
2:36
from 7.95 up to 8.3. After doing so, they were able to measure allegedly 10 more tons of carbon
2:44
entering the water immediately. They then used cutting-edge technology, including autonomous
2:49
gliders, long-range autonomous underwater vehicles, and shipboard sensors to track the spreading
2:55
chemicals. Over the next few days, the scientists measured 10 tons of carbon entering the water as the
3:00
pH increased from 7.95 to 8.3 matching pre-industrial levels. In the best-case scenario, the researchers
3:07
estimate that the sodium hydroxide would absorb about 50 tons of carbon over the next year,
3:12
equivalent to the average yearly emissions of five UK citizens. And this summary, by the way,
3:16
it came to us from the Daily Mail publication, and so that's why they used the average yearly
3:21
emissions of UK citizens as a measurement. But, just for your general reference, the average
3:27
US citizen has about three times higher CO2 emissions per capita compared to the UK counterparts,
3:33
meaning the amount of chemicals that they were able to pour into the ocean over the course of those
3:38
four days, it would absorb enough CO2 to offset a single US citizen, which in and of itself kind
3:45
of exposes one of the major problems with this approach, which is the scalability question.
3:50
The sheer amount of these chemicals that will need to be used every year to make a measurable
3:55
dent in global CO2 levels is enormous. To scale up ocean alkalinity enhancement to a point
4:01
where it could abate industrial CO2 emissions, billions of tons of sodium hydroxide would need to
4:06
be dumped into the oceans every year. And then, if you just think about it logically,
4:11
atop both the cost as well as the feasibility of pouring billions of tons of sodium hydroxide
4:17
per year into all five of the world's oceans, there is the ecological impact. The ocean,
4:23
much like any rainforest is a large system, and you can't expect to just change one variable
4:28
and not have any knock-on effects. Now, for their part, the scientists that are conducting this
4:34
research, they said that their project actually returns the ocean to where it was. They claimed that
4:40
over the last several decades, industrial CO2 emissions have had what they call, quote,
4:45
catastrophic effects on sea life as the acid dissolves marine creature shells, damages coral,
4:51
and even wears away sharks teeth. And so, they're basically saying that increasing the pH level
4:56
would actually walk back some of those changes and restore the natural habitats to how they were
5:01
decades ago. On the flip side, however, the critics, they say that we don't actually know what
5:06
effect this will have in the ocean over the course of time. Quote, the biggest source of controversy
5:10
stems from the fact that the impact a marine wildlife is still largely unknown. Recent studies have warned
5:16
that excessive alkalinity enhancement could affect species growth, metabolism, and biodiversity.
5:22
Additionally, as alkaline substances dissolve, they release trace metals, which could build up in the
5:27
oceans and create an ecological risk. And so, these are the two camps. One is saying that we don't
5:33
know the effects that this technique will ultimately have on the ocean, marine life, and the trace
5:38
metal elements might build up over time and cause a disaster. But in the flip side, the scientists
5:43
pushing for this method and pushing to test it say that it will actually de-acidify the ocean
5:48
and restore the natural habitat to what it once was. And I will mention that there is that
5:53
to support this idea. In the past, there have been some smaller scale examples of using chemicals
5:59
to adjust the pH levels of smaller waterways. Quote, most notably, Scandinavian rivers suffering
6:05
fish declines due to acid rain were heavily dosed with alkaline lime in the 1980s,
6:10
leading to the return of native salmon to Sweden's Atron River. Also, for what it's worth,
6:15
the latest test that took place over in the Gulf of Maine, off the coast of Massachusetts,
6:19
apparently, it showed no immediate negative impact on the marine life that was tested. Quote,
6:24
based on the biological and ecological impact data that we have collected and analyzed so far,
6:29
there was no significant impact of the Loch Ness field trial on the biological community
6:34
using the metrics we measured. And just the fun fact, the Loch Ness project is actually an
6:39
acronym and it stands for the Locking Ocean Carbon in the Northeast Shelf and Slope project.
6:46
And so, there you have it. Another, basically, moonshot project to attempt to, I don't know,
6:52
save the earth and combat climate change. Leave your thoughts in the comments if you think that
6:56
this is a good idea or if it's humans, again, trying to play God with the engineering project.
