Shift change, census

Posted on by

Wind NE 15-20 knots becoming N 10-15 knots in the afternoon. Sky cloudy with periods of rain.

Courtney brought me out this morning in Second Nature to start a 3 month winter shift. She brought Nick back after I was able to get a quick update on systems and supplies.

Census:
California Sea lions: 20
Northern Sea Lions: 155
Harbour Seals: 1
Elephant Seals: 7
Cormorants: 70
Canada Geese: 5
Gulls: 252
Bald Eagle: 1
Harlequin Ducks: 2
Black Turnstone: 2
Sparrow: 1

3 Branded northern sealions observed: 870R, 347Y, and 975? (last symbol not visible)

Spent most of the day moving in, unpacking and getting reacquainted. We brought two full propane tanks out in the morning. Running diesel this evening.

The house is clean and things look to be in order here. Thanks to Nick, Ann, Jeff, Julie, and Courtney for their work out here since my last shift.

Marine Science Students Visit Race Rocks

Posted on by

Coming from Bamfield, I expect large volumes of water when the barometer drops and it starts to blow southeast. It was grey and wet today but the wheelbarrow I left out to collect rainwater only has about 500ml of water in it at the end of the day. The barometer is still sliding so maybe I should be careful what I say. The wind did turn around to westerly for a while as it cleared in the late afternoon and is now flowing out from the northeast with more drizzle approaching real rain. From Environment Canada’s forecast it looks like the trend for this week.

Although there are still plenty of recreational fishers around, only one was noted in the reserve today and they were looking at sea lions. There was only one whale watching boat noted in the reserve.

Laura brought the first of her three marine science classes, from Pearson College to Race Rocks today. Courtney masterfully landed Second Nature at the very unforgiving pier and we had a wonderful field trip with a student:teacher ratio of 4:1. The students were really good at moving with stealth so as to not startle the sea lions. This allowed for good sea lion observations, which were noted in their journals. They saw all four species of Pinnipeds and added to their growing species lists with Black Oystercatchers, Black Turnstones, Glaucous-winged, Heerman’s and Thayer’s Gulls. They spotted new (to me) branded California Sea Lions including three branded in the Channel Islands. All of the students had a bird’s eye view from the top of the light-tower thanks to Courtney and we finished off with warm cinnamon buns at the keeper’s house.

After the visitors left, I caught a glimpse of these two Steller’s Sea Lions entangled in sports fishing gear. Those are salmon flashers hanging out of their mouths, which is not good news, as these cannot be disentangled the way the neck-rings can. The individual with one flasher has been hauling out at this same spot for a few weeks now. The one with two flashers, has not seen before today.

I will be watching out for this animal over the next month.

Today was the first time this animal with two flashes was seen here. It will be easy to distinguish it from the one with only one flasher.

Transition to the last few days of summer.

Today was a transition day with the wind not doing much, but shifting from west-southwest to west and the barometer slowly rising. There were both clouds and low marine air but it did not really rain. The high humidity made it really easy to wash the solar panels this morning and this evening I see hope for a beautiful sunset as it clears to the west. There may be fog in the morning tomorrow but the forecast is for clearing, sunshine and strong westerlies by noon.

Only two whale-watching boats were noted in the reserve today. There was no illegal fishing observed although two boats were speeding in the reserve which has a 7 knot speed limit within 400m of the rocks. Both speeders were sports fishers, one a rental boat from Oak Bay Marine Group 14K40098 and one a commercial charter boat called Cool Change of No Limit Charters 13K1116940.

This what I am looking for when photographing branded animals. This California Sea Lion was branded in the Channel Islands just northwest of Los Angeles.

I managed to photograph a few new (to me), branded sea lions today and got a few more shots with sea lions in the foreground and ships in the background. The Strait of Juan de Fuca is an incredibly busy shipping conduit. I also spent some time organizing data and photographs, a large job that I need to spend more time on. Routine maintenance, cleaning and fighting entropy filled the rest of the day.

There were no visitors today. I would post a sunset photo but it is giving me error messages. As the sun goes down it is beautiful aloft with mauves and crimsons defining perspective on the bottom of the clouds. It is very mysterious looking at water level with a thick fog coming in from the open ocean. The west wind is blowing 17 knots so it will soon be here.

Wetter, cooler weather arrives.

There were definite autumn overtones to the weather today in spite of the westerly winds, which shifted over to the southwest a few times. First thing this morning a heavy fog came in and soaked everything. At dark there were ominous looking rainclouds to the west but the forecast actually looks like it is improving. After a week of sliding downhill, the barometric pressure actually rose today and that is a really good indicator of an improving trend.

There were only six whale watching boats noted in the reserve today and I couldn’t see any whales (for a change). The few recreational boaters left on the water stayed out of the reserve. The Oriole sailed past through Race Passage today, flying with the wind and tide.

A series of large military explosions rocked the island mid-day.

Two Steller’s Sea Lions with Ring-necks were photographed today as was a Steller’s with a green flasher hanging out of its mouth. One of the ring-necked Steller’s is not yet badly wounded by the plastic strap, the other (see photos) has the strap cutting into the back of its neck but not yet the front. This animal likes to sleep about ten meters from my house and would be a good candidate for disentanglement.

There were no visitors today. Maintenance chores, other than making fresh water and electricity included cleaning in the boat shed, mending both houses’ fences, and keeping the weed-eater going. The weed-eater makes really good compost mulch.

Sizzling September

Posted on by

Summer continues on Race Rocks with light easterly winds switching around to westerly this evening. It is still clear but there are more clouds tonight than I have seen in a while. Overall the barometer has been slowly dropping since last Thursday yet still remains relatively high. Although there is a gale warning in effect for tomorrow, the winds will be westerlies, which usually means good weather, but may bring in the fog.

Killer Whales to the south and southwest of Race Rocks drew quite a few tour boats again today. A total of fourteen whale watching boats were observed in the reserve, all well behaved. There was no illegal fishing observed.

Another ring-necked, California Sea Lion was photographed today. It appears to be healing although no rehabilitation tags were observed on this animal and it was difficult to tell if the entanglement was still there or not.

This California Sea Lion appears to be recovering from a ring-neck injury. No tags to indicate rehabilitation.

Unlike some of the ring-neck sea lions this wound appears to be clean and healing.

Most of the sea lions hauled out at Race Rocks appear to be in good shape. Here is a photo of a well fed Steller’s Sea Lion.

The total number of Double Crested Cormorants and flock size, seems to go up everyday. Today I saw my first returning Surf Scoters flying in from the west. Rhinoceros Auklets, Common Murres and Heerman’s Gulls are very active around the edges of the reserve. The Heerman’s Gulls sometimes rest on the big rafts of bull kelp.

The Bull Kelp is on its’ way out and is epiphytized with red and green algae. Much of the area on the large blades have gone into zoospore production and the spore patches are clearly visible.

Bull kelp sporophylls are the lighter areas of the blades. This is where millions of zoospores are produced to make the microscopic over-wintering gametophytes.

This last large tidal series has ‘littered’ the tide lines with floating kelp, wood and debris. A dock with a braced super-structure heading out to sea with the tide in Race Passage was reported as a hazard to navigation.

A lot of maintenance work has been accomplished over the last few days. The Jetty exclusion zone is now working well. The science house perimeter is functional. The weed-eater is working well and the compost is mulched in with hay. Many little things are a bit cleaner and tidier than when they were found.

Super September

It just keeps going, for now. The barometer is not doing much; the gentle outflows are keeping the fog out. The smog from the interior is cranking up the sunsets. It is supposed to change by Wednesday though, so enjoy it while you can.

There were 24 whale watching boats observed in the Race Rocks Ecological Reserve and Rockfish Conservation Area today. Most of them came in the afternoon and spent time to the south of the reserve watching cetaceans before or after coming in to see the sea lions.

Most of the Whale Watching boats are very well behaved and respectful but there are a few boats that may be pushing the boundaries in terms of slowing to 7 knots within the Reserve and/or speeding before leaving the Reserve. The same may be said for dive charters and some sport’s fishing charter boats. The speed limit is 7 knots within the Reserve.

A dive charter operator out of Victoria was back again today with divers and the operator of the vessel sped around the kelp bed, an area with lots of sea lions in the water, after dropping off his divers. In the end he had to come back to the drop-off point to pick up the divers, so not sure what the point was. One Pedder Bay Marine rental boat was reported jigging in the reserve again today.

Maintenance work took priority over observations today and Alex helped with all kinds of entropy-fighting activities including fence mending, moving concrete blocks, and fixing the weed eater. Now I will be able to put aside some hay for composting in the winter without bringing in off-island seeds or continuing to use the little hand scythe. He also contributed some great ideas for improvements like adding vertical rubbing strakes on the jetty, painting a mark on the marine railway carriage to indicate the depth required for loading/unloading the whaler and sending an e-map showing the 40m contour to all the operators who frequent the Reserve.

Thunder and Lightning

It was a dramatic day weather-wise with near-gale westerlies and a heavy downpour that dropped almost one centimetre of much needed rain. Just before the sun went down there were intense rainbows. The barometer continued its slide but a nice sunset and the westerly wind warning, mean sunshine for tomorrow.

With no killer whales in sight, the whale watching boat numbers dropped to three. There were no recreational boaters fishing in the closed Conservation Area today. There were some big blasts from the military site today late morning and early afternoon. They had a vessel standing off to the northwest of the reserve talking to boaters. Although there were no visitors ashore, Second Nature came within a stone’s throw of the jetty and I waved to Courtney and the Pearson College students aboard.

This morning when I got up there were no sea lions on the jetty for the first time so I will continue my territorial patrols. I scanned for brands/tags from the top of the tower again today, and added more to the growing list. Eventually I will put a finders’ curve together to see if I am approaching the asymptote.

I was a bit grossed out to see the GW Gulls and Black Turnstones foraging in the Sea Lion messes this morning. I wonder what their parasite load is mmm? At least one of the sea lions had evidently been eating krill.

All but one of the young gulls are flying now and it was fun to watch them ‘getting a flying lesson’ from the raven this morning. Okay, I know that is way too anthropomorphic. They were all following raven who seemed to be playing the trickster, (maybe hoping they would crash for breakfast). Ravens are so good at doing aerial flips and such but young gulls are still a bit wobbly. There are still two Pigeon Guillemots carrying food to nest sites. they bring a variety of benthic fish: so far I have seen little flatfish, large gunnels a variety of sculpins and maybe a prickleback.

Other than the routine chores, more window cleaning and moving heavy concrete blocks today, I did some trouble-shooting on the computer and deleted over 11,000 items from the trash which sped things up. I started to read the camera manual with camera in hand. Yesterday’s passing Killer Whales inspired me to learn how to use the camera with the big lens.

Recovery of species and spaces at risk.

Another glorious day at Race Rocks with westerly flow, basically a repeat of yesterday weather-wise. The barometer has dropped a bit over the evening and the wind has shifted to the southwest. Here is a graph of the atmospheric pressure that can be pulled up on the racerocks.com website. Tomorrow looks similar, windy with a chance of showers.

There were 33 tour boats today including a few that may not have been commercial. Some of the tour boats are really enormous and barely fit in the passage. There were at least 17 recreational fishers, again with some jigging by the rentals in the closed conservation area. Amazingly, a DFO patrol boat passed by and did nothing while these folks were slaying bottom fish in the reserve. I was up in the tower and couldn’t get the K-numbers as they are only painted on one side of the boat.

I did record another four sea lion brands in between chores and spotting killer whales travelling and feeding from the southwest to the southeast. There was one large bull, one little one with (probably) its mother and at least two others. I wasn’t close enough to identify them but if they were southern residents they are very endangered.

I was thinking about their chances of recovery when I noticed they were perfectly lined up with the Elwha River valley across the Strait in Olympic National Park. It reminded me of that Margaret Mead quote “Never underestimate the power of a few committed people to change the world. Indeed, it is the only thing that ever has.” The recovery of the Elwha ecosystem is a remarkable story.

Not so remarkable, was the rest of my day; cleaning windows, killing flies, trying to learn how to use the camera, attempting to “train” the sea lions to get off the jetty and pursuing the regular drill of fighting entropy.

Fog and sunshine

Posted on by

There was a tiny bit of rain with fog early today and then it switched back to near gale westerlies with heavy fog interspersed with sunshine. It is a beautiful starlight evening and the westerly continues to drop. The barometer held fairly steady today with a slight increase this evening. Environment Canada says that a strong westerly wind warning stays in effect for Sunday with a chance of showers.

There were ten whale watching boats in the Reserve today and they were all well behaved. A dive charter boat with eleven divers aboard came through the reserve but I am not sure where they dove.

Two male kayakers , one in a green kayak and the other in a reddish-brown kayak came through the passage on the south side of Great Race in the early afternoon and caused a sea lion stampede. They then proceeded to fish right in the closed conservation area. There were also two recreational boats fishing in the marine protected area.

A few more sea lion brands were observed today including one seven year-old female Steller’s Sea Lion that was branded as a pup in 2007 at Rogue Reef , near Gold Beach in southern Oregon.

This was my first day to not see Elephant Seals and California Sea Lions have taken over the jetty and marine railway. Some of them are a bit scary looking and do not want to move so that I can do seawater data collection.

Three River Otters were out and about in daylight today. Usually you don’t see them and just guess that they are around in the evening as all the gulls lift off and call. There were two young, very healthy-looking animals with an adult. Maybe that it why there are so many Glaucous-winged gull chick mortalities here? (Just a guess.)

Alex was quite excited to see some of the old lighthouse artifacts including parts of an old Fairbanks-Morris engine. He also pointed out where the old granite light-keepers house had been removed from its attachment to the base of the light tower.

The tasks today were the basic, regular tasks of  cleaning the solar panels, running the generator, launching and bringing the boat back up in order to drop off Alex, repairing the jetty fence (twice) and taking the salinity measurement. Tomorrow is month-end report time.

 

 

Baleen at sunset

Fog in the morning that burned off around 1030h. Winds reached 35 knots mid-afternoon. Light winds forecasted for tomorrow morning and increasing in the afternoon. Barometric pressure still dropping.

Last of the gull chicks are learning to fly. Another elephant seal arrived on the boat ramp today, bringing the number to four. Spotted a baleen whale off the SW side of the reserve at 2030h this evening as the sun set.

Courtney came out in Second Nature with a tour group this morning of alumni and then made another trip to do maintenance on the desalinator (which is now in working order). Cistern was very low so Anne and I ran the pump for most of the day. Continued with Anne’s training.
