August 20 – Two Pods of Transient Orcas!

Posted on by

Wind: W at the beginning and end of day, NE mid morning to early afternoon, 4-18 knots
Sea State: calm
Visibility: 0-10 NM
Sky: fog in morning, clear in the middle of the day, overcast in afternoon, rain in evening
Temperature: 12-17 °C
Atmospheric CO2: 412.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

There was a lot marine mammal activity today. At 11:00, two pods of Bigg’s transient killer whales were in the ecological reserve. One pod appeared to have about six whales. The other pod appeared to have three. Both pods spent a lot of time around the South Islands. A nearby whale watching boat captain mentioned on the VHF radio that the orcas were two families most likely having some social time. They were probably having a good meal too. I didn’t see any hunting happening on the surface. Transients eat marine mammals like seals. I did see a lot of harbour seals not taking any chances, huddled together on nearby rocks and around the east bay beach, looking towards the areas where the orcas were swimming. The transients stayed around until at least 3:30.

See the photos below for views of the orcas and other sights from today:

Wind: yesterday 2-7 knots from NW to SE, today 0-15 knots from N to E
Sea State: both days calm
Visibility: both days 15 NM
Sky: both days clear
Temperature: both days 3-7 °C
Atmospheric CO2: 414.30 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The wind has been relatively calm over the past two days. Along with clear skies, it’s been very delightful here. This morning, the three elephant seal pups began hanging out all together for the first time. I saw their slide marks coming from different directions across the frosty grass towards the bushes in the middle of the island.

This morning at 8:45, I was at the kitchen sink doing dishes and looking out the window, I spotted a pod of orcas splashing just south of the island. When I went out to get a closer look, it appeared the pod of five to seven orcas were hunting a harbour seal or sea lion. The orcas were swimming in circles and splashing around. A few sea lions were looking on from nearby shallower water. The orcas are most likely transient or bigg’s, which hunt marine mammals.

Five visitors from Pearson College were on the island today to remove 16 old batteries and three empty diesel drums. They each weigh 250 lbs, so two trips were made to keep the boat seaworthy. Thanks for the great work Corey, Giovanny, Greg, Jake and Lawrence.

Other than the Pearson boat, there were four boats in the ecological reserve over the past two days. Yesterday, three tour boats stopped by for a look. Today one pleasure craft went through Middle Channel.

See the photos of some views from the past two days:

A short video of the orca pod just south of the island today. I was standing by the surge channel near the Science House. The bird that flies across the frame is a juvenile bald eagle. You can see the sea lions on the left side looking on. The orcas might be hunting a sea lions or seals. I will provide an update if the pod is identified.

The Long Weekend.

Fog followed an overcast dawn and was repetitively beaten back by sunshine throughout the day. While the sun was out, it was intense (900 Watts/meter2), but fog lingered just to the west and Beechey Head was repeatedly obscured as the fog came and went. Eventually in early evening, pushed by the west-southwest wind, the fog rolled back in and enveloped Race Rocks. For most of the day day the wind blew west a fairly steady, 10 – 15 knots. The fog wind was more intense though, pushing 25 – 30 knots. The barometer went up a bit in the morning and then, after noon it dropped by a little more than it had gone up, ending up at ~1014 hPa and falling. The forecast is for a strong wind warning, (more westerlies), mainly sunny, with a few clouds.

No whale watching vessels were observed in the Ecological Reserve today. Several private, sportsfishing boats went through at a respectful speed and they were not fishing in reserve. One rental boat from Pedder Bay Marina was fishing in the Rockfish Conservation Area on both the east and on the west side of the houses. The people seemed to know that they were not supposed to be there and were playing a bit of hide and seek. Two couples were all fishing for and keeping rockfish in the Rockfish Conservation Area (RCA). Whether or not they exceeded the limit for outside RCA (1 rockfish per day) is open for speculation.

Two large male Killer Whales were spotted travelling east, along the north edge of the Ecological Reserve in Race Passage. As is often the case with Bigg’s Killer Whales, they seemed to be evasive, perhaps exhaling underwater. They were spotted again near nNorth Rocks and then skirted around to the south. From their behavious, it is likely that these were Bigg’s Killer Whales.

It takes a lot less energy to play when suspended in water.

The Northern Elephant Seals have been sticking very close to shore during their swims, preferring the shallow sub-tidal in the bull kelp fringes. The young males who love to play fight when they are hauled out continue their sparring activity in the water. I wonder if the Bigg’s Killer Whales could hear them?

Another new (to me) Northern Elephant Seals showed up today, well tagged with #9836 on the right and #9807 on the left. All four tags looked really new as did the seal. The smallest one ashore since I arrived in March, it had almost completed its’ moult and the skin was looking too big for it, so I venture to guees that it has been hauling out on Middle Rock moulting for a while and came over to Great Race because of all the bustling seal activity here.

This small animal is starting to look like her skin is a bit too big for her.

Both routine chores and seasonal maintenance were accomplished today. The grated, aluminum ramp on the jetty was repaired and trouble-shooting completed on the Whaler’s electrical system. There were no new visitors today.

April 9th was a beautiful day.

Except for the chill early and late, April 9th was almost like a summer day. Solar radiation reached a high of ~825 watts/meter2 today, certainly enough to make bull kelp shoot up and solar panels top up batteries. Light airs from the south barely moved the flag most of the day and the westerlies The barometer was fairly steady today but is falling now and the forecast is for increasing cloudiness overnight and rain tomorrow.

There was active whale watching activity today and six tour boat visits observed inside the Ecological Reserve. A pod of four Killer Whales passing just to the south of the Ecological Reserve drew a crowd. There seemed to be a small one that was breaching, a larger sub-adult, a large adult male and a female. I did not see the whales enter the Ecological Reserve.

There was military blasting today on the surface at Bentick Island, from late morning through into the afternoon.

Lots of chores were completed today, including extras like fixing the solar panel squeegee, washing outside windows, fixing another bench, beach-combing and tidying. We rearranged the desk/office area to make it more efficient and ergonomic, stood radio watch for a field trip to Swordfish Island, fixed the phone/internet again with subsequent re-boots of weather system and underwater camera, etc. Internet/phone down again just as I go to post this. Now back up after one last tower visit for the night.

Thursday is Census Day at Race Rocks

The weather was fine today with sunshine from dawn until about four o’clock. Winds were very light and the direction shifted around west, from northwest to southwest. As the barometers drops, rain is forecasted, southeast winds and then improving with only scattered showers by tomorrow afternoon.

The fine weather brought two small sports fishing boats into the Ecological Reserve today, both fishing and speeding inside the Ecological Reserve boundary.  My guess is that neither of them were aware of the Eco-Reserve and its protection from speeding and jigging.

There were three, whale watching boats in Reserve today and several others that passed outside of the boundaries. One of the attractions for the whale watchers were Biggs’ Killer Whales, also known as transients. The ‘T”s as they are known to the tour operators were travelling from west to east when I saw them and they passed very close to the seal haul-out on North Rocks before I lost them to view. It looked like four individuals. I saw a single, adult male Killer Whale two days ago, it was just a one-off sighting and I didn’t spot it again in spite of watching for quite a while. That one was also probably also a Biggs, just from the behaviour.

Today was Mega-fauna census day and here are the results.

What a difference between drake and hen. These 'white water' birds nest in the mountains by rushing streams and rivers.

It was a busy day with lots accomplished. I managed to get the weather station back up and connected to the Internet, thanks to good instructions. I have been on a bit of a wild goose chase, mapping out the nest locations of the Canada Geese. I troubleshot water loss problem (to no avail) and ran both the desalinator and generator. Sweeping the walkways and tidying up wood is ongoing. The census took quite a while and was totally enjoyable. This is such a special place, a real biodiversity hotspot especially underwater. What we see on the surface is like the tip of the biodiversity iceberg or the biomass (food) pyramid. All that biological activity can traced right back to plankton and sunshine that drives it. Sunshine made most of the fresh water today, thanks to the solar panels and desalinator.
