Weather

North wind, 10 knots in the morning.  Stronger Easterly winds up the straight directed swells into the jetty throughout the day.  Wind direction shifted to West in the evening and picked up to over 30 knots with rain. Visibility dropped to around 1 mile in the afternoon.

Ecological: Before dusk I saw a lone humpback whale surfacing near the reserve.

Guy left the station around 800 in the morning. We met around noon at the college and debriefed. I came out in the whaler and landed around 1400.  I will be here for the month of December.

Ecological

  • There were 3 male elephant seals on Great Race when i arrived, 2 of them are adult including Chunk, the other appears to be adolescent.  There was another male elephant seal on West Rock.
  • There are more sealions in the reserve than I recall from previous years at this time and they are more present on Great Race as well,  including a persistent congregation on and around the jetty.

Boats

  •  3 ecotour boats after I arrived in the afternoon.  Two of them appeared to be within 100 m (DFO setback guideline) of sealions.
