Aloha! The 2017 Hawaiian Islands Cetacean and Ecosystem Assessment Survey (HICEAS) is a 187-day survey effort to study cetaceans, seabirds, turtles and their habitat within the U.S. waters of the Hawaiian Islands. This survey effort will occur from July through December aboard two NOAA ships, the Oscar Elton Sette and the Reuben Lasker.

Visiting scientist Joe Fader from Duke University deploys a sonobuoy at sunset. This short-term drifting buoy contains a hydrophone that detects and transmits the low frequency sounds of baleen whales that might be in the area.
Dorsal Fin Decoding
Credit: NOAA Fisheries/Paula Olson (Permit 20311)
We learn a lot about whales and dolphins from their dorsal fins. The large size of this dorsal fin tells us this short-finned pilot whale is a male. The nicks and notches on the trailing edge of his fin form a unique pattern, much like a fingerprint, which allows us to recognize him if we see him again.
Lasker Sets Sail

A large group of Longman’s beaked whales was spotted late in the day, only about 150 nautical miles away from a sighting of a large group of the same species during HICEAS 2010. Could we have found a hotspot for this rare beaked whale?
Late-Night Visitors

Three days into the NOAA Ship Reuben Lasker's transit to Hawaii, the acoustics team detected killer whales in the distance. Unfortunately, it was at 10 PM, so everyone had to make do with watching the computer monitor that displays the vocalizations detected by the towed acoustic array.
Back to the Future

U.S. waters around the Hawaiian Islands extend across the international dateline. We had a chance to “time-travel” on a recent trackline. Much to our surprise and relief, we found that short-finned pilot whales still exist tomorrow, today.
Catch of the Day

An adult red-footed booby, the most common booby species in the Hawaiian Archipelago, catches a flying fish for dinner. These birds capture fish by diving vertically into the water and can dive as deep as 30 meters!
Marine Debris

Short-finned pilot whales are highly social and are usually found clustered together. We spotted a group of whales of different ages.
Distinctive Fliers

Out in the middle of the Pacific it can sometimes be difficult to tell various species of shearwaters or petrels apart, but tropicbirds always stand out due to their white coloration and distinctive way of flying.
The 2017 Lunar Eclipse

Blainville’s beaked whales are shy and elusive creatures, and we often only catch a glimpse of them. Today, however, we were lucky enough to have a group of them hang around the ship, seeming as curious about us as we are about them.
Corn Hole

After many moons at sea, when your entire world exists for only 224 feet in any direction, you come up with fun and imaginative ways to pass the time. Here, officers, crew, and scientists socialize and laugh over a round of corn hole, complete with homemade boards and bean bags.
A Rare Look

A young Longman’s beaked whale surfaces head-first. These whales were exciting to see since they are so rarely encountered.
Spotted Visitors

The Sette and the Lasker pulled into Pearl Harbor on September 5th, which marked a highly anticipated reunion among observers, officers, and crew members. After a quick inport, the collaborative HICEAS team took a photo on September 11th, before both ships sailed away for their next month at sea.
Highest Priority
Credit: NOAA Fisheries/Paula Olson (Permit 20311)
Aboard the Oscar Elton Sette, we started leg 3 with false killer whales–our highest priority species! We will use photos and biopsy samples to determine the population to which they belong (Main Hawaiian Islands, Northwestern Hawaiian Islands, or offshore).
Ever-Present Debris

Two boobies rest atop a mass of nets and line while a huge school of mahi-mahi swim beneath. Marine debris and trash are ever-present in the ocean. NOAA Fisheries and multiple agency partners have conducted surveys and removal of marine debris in the northwestern Hawaiian Islands on a nearly annual basis since 1996.

The blue-gray noddy (Procelsterna cerulea saxatilis) breeds on Nihoa and Mokumanamana (Necker) with 2,500 and 1,250 breeding pairs, respectively. It stays near its nesting colony year-round. It is a graceful, small seabird that feeds on pelagic waterstriders of the genus Halobates, picking them carefully off the water's surface.
Show Us Your Forehead!

It was a blackfish day on the Reuben Lasker! This morning we sighted false killer whales (Pseudorca crassidens), followed by two sightings of short-finned pilot whales (Globicephala macrorhynchus). The pilot whales paid us a visit, passing close enough to the ship so we could take great photos!
Nothing to See Here

This sperm whale calf leaps out of the water multiple times over a 10-minute period. We don't know for certain why they do this. Perhaps to remove a parasite such as a remora, or to communicate about its location by making a big splash and loud sound, or maybe just for fun.
Flying Away!

This black-winged petrel was seen chasing a group of flying squid close to the ship one evening. Black-winged petrels breed in the southern Pacific Ocean, but spend their winter north of the equator. The flying squid use propulsion to fly out of the water, likely to avoid predators.
Mahi on Surveillance Duty

The in-line array was attacked overnight by a cookie cutter shark (1; Photo: NOAA Fisheries/Jessica Chen) that left a gash in the rubber tubing about the size of a quarter (2-3) causing the castor oil inside to gush out. The tube was fully drained of oil to make sure that saltwater didn't do any damage (2). The tube had to be replaced and was removed, leaving the "guts" of the array on the table (4). Jennifer Keating soldered the wires back to the connector (5) and tested to make sure that the connections were good (6). Jennifer and Erik Norris refilled the new tube with castor oil (7) and the fully repaired array was redeployed (8); all before lunch!
Just a Typical Day on Kure

Humpback whales have arrived in the Northwestern Hawaiian Islands! We saw the first juvenile humpback off Kure on September 26 and this juvenile humpback off Pearl and Hermes on September 28.
Welcome to Tern Island!

French Frigate Shoals (Kānemiloha‘i) is the largest atoll in the Northwestern Hawaiian Islands (232,000 acres). Tern Island, a part of the atoll, was made into a runway during World War II and was used as a fueling stop for military planes flying to Midway. Today it is the location of the base camp for monk seal and turtle researchers during May to October.
Birds on Tern

The Sette's deck crew and PIFSC scientists work together to remove all monk seal and turtle camp supplies from Tern Island. A small boat was launched from the ship and made multiple trips over the period of a day and a half. Buckets of gear are lifted onto the ship by a simple line (rope) and cargo hook.
Whale Shark!

Like many dolphin species, false killer whales like to bow-ride, a behavior where the animals let the pressure wave in front of a ship help push them along.
A Common Visitor...or Is It?
Credit: NOAA Fisheries/Bernardo Alps (Permit MB033305)
Observers from the NOAA ship Reuben Lasker have seen red-footed boobies regularly; they like to hang around and catch flying fish flushed out of the water by the approaching vessel. This white-morph individual has a dark tail, indicating that it is the subspecies websteri, commonly found off Central and South America, rather than the subspecies rubbripes, which is expected around the Hawaiian archipelago.
Eye-Catching Orange
Credit: NOAA Fisheries/Bernardo Alps (Permit MB033305)
Although superficially similar to the more common masked booby, this bird has an orange rather than a yellow bill, indicating it is a Nazca booby. This species breeds on the Galapagos Islands and off Central America. As far as we could determine, this is only the sixth record in Hawaii.
Floating Treasure
Credit: NOAA Fisheries/Bernardo Alps
Unfortunately, we find many man-made objects floating in the waters of the Hawaiian Islands EEZ, but we get excited when we spot a Japanese glass fishing float like this one. This kind of float is no longer used in fishing, but there are still some carried by the currents in the North Pacific Ocean.
Leaping Fraser's Dolphins

October 21st marked the third encounter with Fraser’s dolphins for HICEAS 2017, and it was exciting to see these rare dolphins. Beautiful Fraser's dolphins are a treat to watch and often leap out of the water in a coordinated, "chorus-line" manner.
A Beaufort 7 Sort of Day!
Credit: NOAA Fisheries/Lauren Jacobsen
On October 23rd, the NOAA ship Reuben Lasker trekked through Beaufort 7 conditions, with 12-foot swells and 30-knot winds. These swell and weather conditions are not conducive for visual or acoustic detections, but instead result in a “weather watch” where one observer monitors the weather for improved conditions in hopes of resuming search effort.
Diving Deep

A rare photo of a pygmy sperm whale (Kogia breviceps). Pygmy sperm whales are hard to photograph because they are difficult to spot at sea and avoid vessels. They are typically found alone or in pairs, and moves inconspicuously by rising to the surface and dropping back underwater with little splash.
Left Wing Graze

Whether or not a day at sea is lucky to include a cetacean sighting, various species of birds are seen from the ship. On this day, this gorgeous white-necked petrel was photographed from the ship as its left wing grazes the water.
Coming Up for Air

On November 17, we encountered a large dispersed group of false killer whales - the ship was surrounded by some unknown number of subgroups. In addition to sightings from the ship, we launched the small boat and collected three biopsies and close photographs for individual identification.
Majestic Backdrop

Black-footed albatrosses nest on the Northwestern Hawaiian Islands, but feed mainly in the Gulf of Alaska and the California Currents, where they learn to follow ships and feed on discards from fisheries and trash. This individual was probably following the NOAA ship Reuben Lasker hoping for a similar feeding opportunity.
Keep Your Eyes on It

Crew, officers, and scientist have a Thanksgiving dinner far from home but in the company of friends. The mess hall of the ship was decorated for the occasion and the dinner included turkey and all the trimmings.
Deploy. Retrieve. Repeat.
Credit: NOAA Fisheries/Bernardo Alps
Acoustician Jennifer Keating retrieves the acoustic array at the end of the day on the fantail of the NOAA ship Reuben Lasker. The array contains a set of specialized hydrophones (underwater microphones) and is responsible for many detections of marine mammals. It is retrieved and deployed multiple times per day for various reasons, such as before every CTD cast (conducted twice per day), during rough weather conditions, prior to small boat launches, and to conduct acoustic array maintenance.
Artistic Effect
Credit: NOAA Fisheries/Bernardo Alps (Permit 20311)
A rough-toothed dolphin appears distorted like a modernist painting, caused by the refraction on the surface of the water as the dolphin rides the bow of the NOAA ship Reuben Lasker. When ships and boats move through the water, they create a pressure wave that pushes dolphins along, much like a surfer rides an ocean wave near the beach.
