MARINE LIFE DISTURBANCE: If you are checking out camera 1 or the remote camera today, you probably noticed that the middle island was full of sea lions this morning and was completely empty by noon. The Department of National Defence is doing their blasting exercises today again over at Bentinck Island . They will be doing the same tomorrow. A rather tragic occurance that happens every fall. Eventually the Northern Sea Lions (endangered species) and the Californian Sea Lions just move out of the Race Rocks area. There is a video on the marine mammals archive page that shows the effect of the Oct 7 blast. We have recorded todays events, (so far seven blasts) and will have it up in the archives also in a few days. In the meantime, look at the before and after pictures taken from the sitezap robotic camera just before and after noon today. This will appear in a file at http://www.racerocks.com/racerock/marmam/sealion/dndblastnov7.htm

Sea lion population still down
Good Evening
TEMPERATURE: Max. 9.5 ºC »» Min. 4.9 ºC »» Reset 7.9 ºC
MARINE LIFE: The population of Sealions is still down since the last series of blasts so it is fairly quiet,the animals hauled out by the winch house are quite nervous of any activity on or near the dock. With another series of blasts in the coming weeks they may just move away altogether. Saw only 5 small fish balls today and not many birds feeding, seem to have followed the food elsewhere for now. The geese were back, at least 6 of them.
HUMAN INTERACTION: The LGL observers arrived first thing this morning and left at 16:30 and as careful as they were the sealions closest to the dock took to the water.There were 8 Ecotour boats through today.

Sealions still scared off by DND blasting
Good Evening
TEMPERATURE: Max. 8.0 ºC »» Min. 4.9 ºC »» Reset 7.1 ºC
MARINE LIFE: Still large numbers of sea birds but the fish balls are fewer and less frequent. Did see a Harbour seal catch a fairly large salmon along the dock on the west side. The activity attracted a hundred or more gulls,some we lucky and flew off with nice pink chunks of fish. The seal made short work of the salmon then hauled out on one of the flat rocks to rest and digest it’s meal.The number of Sea lions hauled out is down dramatically although the conditions are very good, lots of food and calm weather. The one major problem is the effect of the blasting.These animals were getting used to the boat and people traffic but are now very stressed and spook very easily. So much for referring to this MPA as a wildlife refuge where the animals can expect to hunt, feed, communicate, socialize, rest etc. without disturbanceand interference.
HUMAN INTERACTION: There were 6 Ecotour boats and 4 pleasurecraft. The station boat made a trip to Pedder Bay and back

LGL does contract for DND on Blasting
Good Evening

MARINE LIFE: The California Sea Lion with the injured hind flippers is still hauled out on the dock and keeps to it’s self. The poor animal is most likely in pain- looks quite thin, probably not able to manouever too well to catch it’s food.
HUMAN INTERACTION: 6 Ecotour boats, LGL observers boat. The Second Nature made two trips, one about noon With Garry and his class then again with Garry, Scott and Don to work on Camera # 2 system.
MARINE LIFE: (Reported by Garry Fletcher) I had the opportunity to be at Race Rocks twice today. On first arriving at 11:45 AM it was obvious that the DND had been conducting their explosions on Bentick island. We have gotten used to the sealions building up their numbers over the past few weeks. The main island to the East of the House , and the whole northeast front have been covered with animals throughout the daytime. The major concentration however has been on the middle island, which if you have been checking on camera 1 these days has been covered with a mass of bodies. By 11:45 today most of these areas were bare.. only a few brave individuals had crawled back up on the rocks we will see tomorrow how many have returned, but if it follows the patterns of other years, their numbers will start to taper off if the harassment continues. This year the DND has decided to check out our allegations of harassment of these endangered species — yes that is the category the Northern Sea Lions now occupy in Canada. A contract has been let to the consultants of LGL to survey the effect of disturbances, so they have had observers in the tower on the two occasions of blasting this fall. Today the result was obvious. The irony does not escape one that this is an ecological reserve, an MPA and even that does not protect endangered species in Canada.. For a video of the effect of a blast on the behaviours of the birds and mammals at Race Rocks, go to one I recorded on October 7 – its in the marine mammals archive at: http://www.racerocks.com/racerock/archives/viddndblast.htm

DND Blasting Disturbs Sealions
Good Evening
TEMPERATURE: Max. 10.7 ºC »» Min. 8.3 ºC »» Reset 9.7 ºC »» Rain 0.6 mm
MARINE LIFE: Another unsettled day for the wildlife with another day of blasts at DND. The fog rolled in very thick last night and until just after noon we were only able to observe the sea lions and Harbour seals along the north shore of Great Race.The first blast at about 10:12 alerted the sea lions, the second blast about 1 minute later sent 35 of the 79 sea lions hauled out prior to the blasting into the water, of the 13 Harbour seals hauled out in the dock area 2 took to the water on the first blast,9 on the 2nd blast, the birds that we could see took flight ‘en masse’ and most settled back down fairly quickly. The second series of 2 blasts was approx 1 hour later and 9 more sea lions went into the water from those hauled out along the north of Gr. Race. The sea lions were unsettled the rest of the afternoon. Most of the Northern S.Lions stayed in the water swiming about in groups of 5 to 12. The ones still hauled stayed close to the water, they were very agitated, there was a lot of noisey head butting.Most days, left undisturbed the sea lions are fairly quiet. Just around 17:00 a small group of Orca appeared along the northeast boundry of the reserve, looked to be T10 and T11 group. There were a lot of seals and sea lions in the water, several groups of Northern S.L very close to the whales but did not see any hunting action. The Orca disappeared as quickly and quietly as they had appeared. There were 9 Ecotour boats and 3 pleasurecraft in the reserve today.

Effect of DND Blasting on Bentinck Island on Sea lion Behaviour at Race Rocks
This video was made on October 7, 2002 in order to document the effect of the Department of National Defence demolition exercises on Bentinck Island on the behaviour of birds and marine mammals at Race Rocks MPA. In previous years we have observed considerable disruption by military exercises involving blasting on nearby Bentinck Island in the fall just after the sea lions have returned to the island. We have requested that blasts be spread out over a longer period of time during an exercise. Traditionally blasts have come in a series of three. The first one would alert the sea lions, the second would send a few in the water and the third would clear the islands. This year on this one occasion, only two blasts were held at five minutes apart. The results are shown in the video.

DND Blasting
TEMPERATURE: Max. 13.7 ºC »» Min. 10.1 ºC »» Reset 10.3 ºC »» Rain 0.2 mm.-2002-10-07′, ’23:42:00′, ‘First day since the sealions have returned this fall that the DND has conducted Demolition exercises at Bentinck island video archive at http://www.racerocks.com/racerock/archives/viddndblast.htm‘,
MARINE LIFE: With the blasting on Bentinck the sea lions were unsettled, ‘barking and growling’ well into the afternoon. At each blast the birds all took flight but returned fairly quickly. There is a juvenile Heermann’s gull with a broken wing, one California S.L. with a 16 cm scar near the right shoulder which looks fairly well healed. A Blue Heron spent some time sitting in the various kelp beds around Gr. Race, it was most likely here for the fish,as there is still a good supply of feed judging by the numbers of gulls and cormorants feeding. The seals and sea lions are catching some good sized salmon as well.
HUMAN INTERACTION: The LGL monitoring crew docked first thing in the morning, Garry over in Hyaku for most of the afternoon filming. There were 7 Pleasurecraft and 6 Ecotour boats through the reserve today.

Westmont School, for the 10:00 AM live webcast
Tuesday, June 11, 2002
Good Evening:
TEMPERATURE Max 15.C Min 9.2C Reset 9.2C
MARINE LIFE: A fairly quiet day on the island, perhaps due to the heavy fog which came several times. Two Bald Eagle visits this morning, however none this afternoon. A very low tide revealed some sun bleaching on the surf grass in the low intertidal. The Goslings are quite large now, perhaps double their size of last week. It is a shame to note that we saw no Sea lions today, they have not been present since the DND blasting a few days ago.
HUMAN IMPACT: 7-8 ecotourism vessels today, despite the fog. Second Nature emerged from the fog to dock with Garry and another group of 4 school children from Westmont School, again for the 10:00 AM live webcast. Garry noted that he had never seen the fog as heavy as this morning. Within a half hour it lifted. Zodiac was taken out twice in the afternoon. The divers went in around the docks at 18:30.

TEMPERATURE: Max. 12.0 C Min. 11.0 C Reset 11.0
MARINE LIFE: Early this morning one Bald Eagle flew around the Gulls nests, spending around 10 minutes looking for prey, despite the constant harassment by the Gulls. The eagle flew of to the west, and was out of site. Perhaps an hour later two Bald Eagles were spotted hunting together, they brought down a Glaucous-winged Gull and one eagle was seen carrying a Gull wing away. There was also other interesting bird action mid-morning. A Turkey Vulture was flying about in the strong winds, attempting to find food. The winds were a challenge for the vulture, with the bird struggling in the gusts. It was particularly noteworthy that the Black Oyster Catchers made a great effort to harass the vulture. This was caught on video just before the divers entered the water and can be seen at http://www.racerocks.com/racerock/archives/vidbenmovie.htm The divers reported an abundance of sperm and eggs in the nutrient rich water off the docks.
HUMAN IMPACT: No whale watching activity within the reserve today. Indeed the strongs winds, 25-35 knots, kept most vessels away. Hyaku docked twice, bringing equipment and materials for the web-cast and conduit repairs. One major disturbance was the Defence Forces Blasting on Bentinck Island which clearly frightened the Sea lions into the water, Around 10 of the 12 Sea lions disappeared within the first two blasts, approximately 10:30am, and have not yet returned. (Note: As of June 18- they have not returned- will not be back until August now. ) .The three blasts with only a few minutes spacing sent shock waves that rattled the house and were not at all pleasant.

Hummingbirds and Black Brants
Saturday, May 11, 2002
Good Evening
TEMPERATURE: Max. 12.0 C Min. 7.3 C Reset 10.1 C
MARINE LIFE: 2 mature Bald Eagles today, still the 3 geese.There is a lot of bird activity and it is never quiet.Today we saw the usual gulls,oyster catchers,eagles,pigeon guillemots, geese, starlings, crows and savannah sparrows. An added bonus were the 2 humming birds that buzzed around for 20 minutes or so, always amazed to see them so far from the mainland but do see a few every year especially if the winds are light. A couple of black brant geese landed in the small bay on the east side of Gr. Race but did not stay long.
HUMAN INTERACTION: 5 pleasure craft and 13 ecotour boats, the last two enjoyed a beautiful sunset as they left the reserve.The D.N.D. did some blasting on the beach on Bentinck Island between 17:30 and 22:00 but only two blasts about 20:20 and 20:25 were big enough to have any noticeable impact here.The birds took flight en masse each time and took 10-15 minutes to settle down,it was getting too dark to see much beyond Gr. Race.
