I want to ask a dumb question: if it was known that this area was high traffic, why are archaeologists only just now discovering these wrecks? Is it not obvious to search this area for wrecks given its history? The article hints that climate change is increasing urgency. Is the case here that we knew there should be wrecks here, but climate change made the search happen?

I've actually had this conversation before with an archeologist with some naval archeology experience.
Shipwreck hunting is ridiculously expensive. The resources required to exhaustively explore 100 sqm of space is probably 1000x of the resources required to do it on land. There aren't any easy shortcuts: radar doesn't work underwater, sonar does but is extremely low resolution, lidar works pretty well but only if the water is very shallow and clear, underwater drones have extremely limited mobility and communication capability. A lot of funding in archeology tends to go to easier or higher probability wins, which has mostly been aerial lidar in heavy vegetation areas for the past 10-15 years.
The best shipwreck hunters rely almost entirely on probabilistic models for where they might find shipwrecks, and the most useful probabilistic models have all developed in the last 30-40 years. In fact, some of the best probabilistic models like Bayesian Search Theory actually originated as a formalization of heuristics that were already used in treasure/shipwreck hunting.
In that respect, I would argue that this find is actually the result of recent advances in probabilistic modeling (along with other advances in data engineering with respect to extremely messy historical data sources) that have just barely gotten accurate enough to start getting the funding it needs to do the harder work of actually working on the sea floor.

It's also worth remembering how little money goes into archaeology in general.
I can think of two nationally-significant archaeological sites in Central Europe - both were partially excavated about fifty years ago, to varying but fairly limited degrees, and then gently reburied, because there wasn't enough money to keep things going.
The site of one has a poorly-trafficked tourist centre today, the other is a clearing with nothing more than a tourist plaque. Both are likely candidates for previous capital cities, so they are obviously significant, but the money just isn't there to do anything about them. I seem to recall reading somewhere that over 90% of one of the sites remains unexcavated.
These are land sites, so relatively inexpensive compared to sea sites. If this is how willing we are to fund nationally-significant land digs, I imagine sea archaeology would be comparatively even more impossible to fund.

Are the location names and country a secret you are trying to keep?
While I can't speak for these wrecks specifically, archeology as a field is chronically underfunded. They have to pick and choose their battles.

That's the main reason. Also marine archeology is expensive. I once heard an archeologist saying that if the rests have passed centuries underwater, one more is less harmful than looters.

Underwater sites are particularly harder to protect from looters than above / underground sites. If the stakes are high enough, scuba diving is a reasonable option for the criminally minded.
It wasn’t long before Costa Concordia was looted for its treasures.

There are VASTLY more interesting archeological sites than the world has resources to investigate!

Yes, the priorities are rather to invest into expensive hardware, to blow up interesting archeological sites.

Fun facts, Gibraltar was named after Tariq ibn Ziyad, a famous muslim Berber commander of the Umayyad Caliphate that conquered most of the Spain and some part of French territories in the early 8th century CE [1].
Then after the conquest, came the exiled young Umayyad prince (escaping from by the later Abbasid Caliphate), who settled in Spain to create a long lasting around 800 years (that's more than European living in America now) muslim Spanish empire with its knowledge center in Toledo. This center contains many books translations and also many new books by muslim scholars. Famous books examples including Almagest Arabic translation that was copied and translated further into Latin, and studied by Copernicus and Galileo [2]. Of course they are other muslim astronomy books and ideas that Copernicus and Galileo studied and copied but never cited properly [3].
Another famous book is Muqaddimah by Ibnu-Rushd or Averroes that's widely considered as the very first work dealing with the social sciences of sociology, demography and cultural history [4].
This center was later captured in 11th century CE, and this event essentially started the Western Renaissance movement in Europe.
Legend has it, in order to motivate his troops, Tariq ordered to scuttle their entire ships armada, before advancing into Spain [5]. Perhaps some of the sinked ships are part of Tariq's original armada, but these ships were intentionally sinked not by accidents.
His act of bravery were copied and followed by later Spanish conquerers but as usual it's not been properly credited to Tariq's original efforts [6].

This is off topic, but is it legal for websites to ask me to either accept tracking or pay? I thought the GDPR made tracking truly optional.
victorbjorklund 2 hours ago [-]
It is a gray zone. Some national regulatory agencies has said ”pay or consent” is compatible with GDPR and some have said it is not. It hasn’t yet been tested by the EU court.
