A weighty projection by the brings urgency to the need for robust, coordinated ocean observing systems across the blue planet: By the year 2100, if no significant changes are made in how we monitor and safeguard marine life, more than half of the world鈥檚 marine species may stand on the brink of extinction.
Just like for weather forecasting, long-term observing systems provide the critical scaffolding that helps scientists and managers make projections of the state of the ocean--pinpointing which areas of the ocean, and which species, require the most attention. Thankfully, there is a basic infrastructure of coordinated networks of observation platforms around the world. In the U.S., this includes the (IOOS), which launched a decade ago.
However, a recent shows how inadequate this is to understand how marine life is changing at the scale of ocean basins and the global ocean. For oceanographers, it鈥檚 akin to the famous call from Apollo 13: 鈥淗ouston, We鈥檝e Had a Problem.鈥
鈥淥ur assessment indicates that the groups that conduct ocean observing around the world are largely uncoordinated, which results in a failure to deliver critical information required for informed decision-making,鈥 states Erin Satterthwaite from , the study鈥檚 lead author. The team 鈥 a whopping 41 coauthors strong 鈥 includes Research Associate Enrique Montes and Professor Frank Muller-Karger from the 国产短视频College of Marine Science.
Representing organizations from Kenya to California, the team identified 203 long-term (>5 years) observing programs that systematically sample marine life.
鈥淲e are very thankful for people involved in these scientific and monitoring programs for participating in surveys like these. Just knowing who is operating in which ocean area is an important step to start to coordinate and build a network that is useful to people in general,鈥 said Muller-Karger.
In total, these programs covered a mere 7 percent of the ocean surface area. Most are concentrated in coastal regions of the US, Canada, Europe, and Australia. That leaves big holes off South America, Eastern Europe and the Caspian Sea, Asia, Oceania, Africa, the Arctic, and in the deep oceans 鈥 where who-knows-how-many species exist. Even worse is the lack of consistency in observations over time; different programs make measurements at very different intervals, ranging from every few weeks to every few years.
Even amongst the platforms that exist for that small percentage of the ocean surface, the programs were not well connected. They use different methods to make measurements, format the data different, and use different databases for data storage. Plus, a large number of programs don鈥檛 share data externally or with the public.
鈥淎 major area for improvement is in the way the data are collected and shared as part of the ocean observing platforms,鈥 said Muller-Karger. 鈥淔or data to be useful it needs to follow FAIR principles: it must be findable, accessible, interoperable, and reusable.鈥
In total, the team summarized its recommendations in the following figure:
These programs are critical to food security, human health, coastal protection, tourism and recreation, and more, said Muller-Karger. 鈥淲e certainly can鈥檛 monitor the entire ocean 24/7/365, but we can and must make strides in making the data we can collect as actionable as possible.鈥
