Monitoring this fleet requires more than AIS. It demands fused visibility across satellite, uncrewed, crewed, and subsea systems — from the GIUK Gap to Gibraltar.

⚠️ Note: Connectivity on internet provider StormFiber (AS9541) in #Pakistan remains dimished 28 hours after a disruption attributed to an incident on the PEACE subsea cable

Graph from NetBlocks showing network connectivity by provider in Pakistan from October 17, 2025, to October 21 2025. The y-axis represents normalized connectivity, ranging from 0% to 100%, and the x-axis represents the dates. The green line representing operator StormFiber (AS9541) connectivity remains stable at around 100% throughout most of the time period, with a sharp drop on October 20. The drop in connectivity aligns with a fault at the PEACE subsea cable. Near total recovery followed by a second drop is visible. The minimum and current connectivity levels are indicated as 36% and 60%, respectively. The chart has a dark background.

Converge and Grid Telecom announce plans to boost international subsea connectivity

Two major international subsea cable connectivity announcements have just been made – both of them relevant to developing markets. One, not too surprisingly, comes from the Philippines. However, the other has a starting point in Greece – on the island of Crete.

Two ways to look at it. In the early life of the asset (0-20 years) most O&M cost is from inspections (minor repairs the rest) - so you get a gain there because you are doing less subsea inspections (costly).

20 years+ your cost is hardware failure rates. This is where, IMO, this fails.

And lastly for now, subsea methane seeps are also observed to be going up elsewhere. Like off the Pacific coast of North America. Previously thought rare, thousands of seeps have now been documented.

www.pmel.noaa.gov/news-story/s....

The U.S. West Coast continental shelf is known to host methane bubble streams, formerly thought to be rare. However, results of a recently published paper indicate that nearly 3,500 methane bubble streams, clustered into more than 1,300 methane emission sites, emanate from the seafloor from the Strait of Juan de Fuca in the north to the Mendocino Fracture Zone off northern California in the south, in an area known as the Cascadia Margin. Derived from data…

Ok. So let’s go to the IPCC report itself which is here:

www.ipcc.ch/report/ar6/w...

The section pertaining to methane hydrates/clathrates is:

“5.4.9.1.3 Methane release from clathrates”

I screenshot the relevant parts.

“The total global clathrate reservoir is estimated to contain 1500-2000
PgC (Archer et al., 2009; Ruppel and Kessler, 2017), held predominantly in ocean sediments, with only an estimated 20 PgC in and under permafrost (Ruppel, 2015).

The present-day CH4 release from shelf clathrates is <10 TgCH4yr-1
(Kretschmer et al., 2015; Saunois et al., 2020). Despite polar amplification (Chapter 7), substantial releases from the permafrost-embedded subsea clathrates is very unlikely (Minshull et al., 2016; Malakhova and Eliseev, 2017, 2020).”

“This is consistent with an overall small release of CH4 from the shelf clathrates during the last deglacial transition, despite large reorganizations in climate state (Bock et al., 2017; Petrenko et al.,
2017; Dyonisius et al., 2020). The long time scales associated with clathrate destabilization makes it unlikely that CH4 release from the ocean to the atmosphere will deviate markedly from the present-day value through the 21st century (Hunter et al., 2013), corresponding to no more than additional 20 ppb of atmospheric CH4 (i.e., <0.2 ppb yr").
