In the balmy, rich waters of the Gulf of Panama, hundreds of humpback whales gather to feed and mate. But this sunny spot isn\u2019t just a refuge for the southern hemisphere\u2019s mighty whales, it is also the Pacific end of the Panama Canal. This shipping superhighway sees more than 36 ships ply its waters each day, including massive cargo vessels weighing hundreds of thousands of tonnes. Until recently, unregulated shipping patterns caused whales and ships to frequently collide, damaging vessels and injuring or killing the animals. From 2009 to 2012, there were 13 whale deaths<\/a> in the gulf, many thought to be the result of ship strikes.<\/p>\n

Fortunately, a combination of solid whale biology and regulations passed by the International Maritime Organization (IMO) has resulted in a scheme that has lessened the frequency of those ship strikes, and is now being expanded to other countries. These traffic separation schemes (TSS), which require ships entering and leaving the Panama Canal to follow specific routes, are estimated to have cut the potential for whale strikes by as much as 92 percent, says H\u00e9ctor Guzm\u00e1n, a marine biologist at the Smithsonian Tropical Research Institute\u00a0in Panama whose research was crucial to the development of the new regulations.<\/p>\n

Nearly a decade ago, Guzm\u00e1n and his colleagues began to use satellite beacons<\/a> to track 15 humpback whales in the Gulf of Panama, and overlaid their tracks with transit records for nearly 1,000 ships. They found that because there was no set path for ships to take as they entered the canal, whales and ships frequently came into contact. Further research showed that during one 11-day period, whales and ships moved within 200 meters of each other 98 times.<\/p>\n

\u201cThis started as basic, fundamental research,\u201d Guzm\u00e1n says. The next step was to find partners to do something about it. Guzm\u00e1n worked with Panama Canal pilot Fernando Ja\u00e9n, the Panama Canal Authority, and a range of other stakeholders for two years to refine a proposal to keep ships away from the majority of the known whale concentrations.<\/p>\n

In 2013, they took the proposed TSS to the IMO, the United Nations agency responsible for shipping safety and marine protection. The proposal was adopted in December 2014, and global shipping charts were updated to reflect the now-mandatory shipping lanes. The IMO also requires ships to move no faster than 10 knots in the area from August to November, when humpback whales tend to congregate in the gulf.<\/p>\n

So far, the regulation has been working. \u201cFrom ship tracking, we know we\u2019ve had 100 percent compliance,\u201d Guzm\u00e1n says.<\/p>\n

Guzm\u00e1n is now studying whales all along the Pacific coast, from the Gulf of California to Chile, and helping countries establish their own TSS. According to an IMO spokesperson, Costa Rica\u2019s first TSS, a two-way lane in the Golfo Dulce, is expected to be submitted to IMO for approval soon.* An area to be avoided by ships off the Pen\u00ednsula de Osa (a feeding and breeding ground for whales) has already been adopted and came into force on 1 January 2018. Peru has plans to submit a proposal to the IMO by the end of 2018 as well.<\/p>\n

Right now, Guzm\u00e1n is busy surveying blue and fin whales off Chile to provide the raw data that will eventually feed into a new scheme.<\/p>\n

\u201cThese things take years, so you really need to have passion to push them through,\u201d he says.<\/p>\n

Correction: This story originally got Costa Rica’s two protected areas backwards. It said the Golfo Dulce TSS was already approved, while a plan to protect the\u00a0Pen\u00ednsula de Osa was to be submitted soon, when in fact the reverse is true.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
