Hello from the R\/V Bell M. Shimada<\/em>! We are currently sampling at an inshore station on the Heceta Head Line, which begins just south of Newport and heads out 45 nautical miles west into the Pacific Ocean. We\u2019ll spend 10 days total at sea, which have so far been full of great weather, long days of observing, and lots of whales.<\/p>\n\n\n\n

Run by NOAA, this Northern California Current (NCC) cruise takes place three times per year. It is fabulously interdisciplinary, with teams concurrently conducting research on phytoplankton, zooplankton, seabirds and more. The GEMM Lab will use the whale survey and the krill and oceanographic data to fuel species distribution models as part of Project OPAL<\/a>. I\u2019ll be working with this data for my Ph.D. with Dr. Leigh Torres and Dr. Kim Bernard, and it\u2019s great to be getting to know the region, study system and sampling processes.<\/p>\n\n\n\n

I\u2019ve been to sea a number of times and always really enjoyed it, but this is my first time as part of a marine mammal survey. The type and timing of this work is so different from the many other types of oceanographic science that take place on a typical research cruise. While everyone else is scurrying around deploying instruments and collecting samples at a \u201cstation\u201d (a geographic waypoint in the ocean that is sampled repeatedly over time), we– the marine mammal team– are taking a break because we can only survey when the boat is moving. While everyone else is sleeping or relaxing during a long transit between stations, we\u2019re hard at work up on the flying bridge of the ship, scanning the horizon for animals.<\/p>\n\n\n\n

<\/p>\n\n\n\n

During each \u201con effort\u201d survey period, Dawn Barlow and I cover separate quadrants of ocean, each manning either the port or starboard side. We continuously scan the horizon for signs of whale blows or bodies, alternating between our eyes and binoculars. During long transits, we work in chunks \u2013 forty minutes on effort, and twenty minutes off effort. Staring at the sea all day is surprisingly tiring, and so our breaks often involve \u201cgoing to the eye spa,\u201d which entails pulling a neck gaiter or hat over your eyes and basking in the darkness.  <\/p>\n\n\n\n

Dawn has been joining these NCC cruises for the past four years, and her wealth of knowledge has been a great resource as I learn how to survey and identify marine mammals. Beyond learning the telltale signs of separate species, one of the biggest challenges has been learning how to read the sea better, to judge the difference between a frothy whitecap and a whale blow, or a distant dark wavelet and a dorsal fin. Other times, when conditions are amazing and it feels like we\u2019re surrounded by whales, the trick is to try to predict the positions and trajectory of each whale so we don\u2019t double-count them.<\/p>\n\n\n\n

Over the last week, all our scanning has been amply rewarded. We\u2019ve seen pods of dolphins play in our wake, and spotted Dall\u2019s porpoises bounding alongside the ship. Here on the Heceta Line, we\u2019ve seen a diversity of pinnipeds, including Northern fur seals, Stellar sea lions, and California sea lions. We\u2019ve been surprised by several groups of fin whales, farther offshore than expected, and traveled alongside a pod of about 12 orcas for several minutes, which is exactly as magical as it sounds.<\/p>\n\n\n\n

Notably, we\u2019ve also seen dozens of humpbacks, including along what Dawn termed \u201cthe humpback highway\u201d during our transit offshore of southern Oregon. One humpback put on a huge show just 200 meters from the ship, demonstrating fluke slapping behavior for several minutes. We wanted to be sure that everyone onboard could see the spectacle, so we radioed the news to the bridge, where the officers control the ship. They responded with my new favorite radio call ever: \u201cRoger that, we are currently enamored.\u201d<\/p>\n\n\n\n

Even with long days and tired eyes, we are still constantly enamored as well. It has been such a rewarding cruise so far, and it\u2019s hard to think of returning back to \u201creal life\u201d next week. For now, we\u2019re wishing you the same things we\u2019re enjoying \u2013 great weather, unlimited coffee, and lots of whales!<\/p>\n","protected":false},"excerpt":{"rendered":"
