High on Big Sisters Island

An evening survey of Big Sisters Island, now part of the Sisters' Islands Marine Park.

Alas, the tidal predictions were way off and the waters didn't receed. It was also very windy, making photo taking a challenge. But I had a glimpse of some corals and marine life.

Cyrene: seagrasses back, but no knobblies?

We're back on Cyrene Reef in glorious weather. It must have been drizzling or raining in the distance, because we saw a lovely rainbow!

It was great to see the seagrasses coming back in the deep pool. But worrying that none of us saw the mass gathering of large Knobbly sea stars that Cyrene is well known for.

Changi Creek one month after oil spill, with otter!

One month after the 300-tonne oil spill in the East Johor Strait, signs of the oil spill remains at Changi Creek near the Changi Point Ferry Terminal.
Oil stains on Changi Creek seawalls
There is some improvement compared to our last oil spill impact survey in Jan 2017, about two weeks after the oil spill. Although the band of oil stain is still clearly visible, I couldn't smell the oil from above the seawall. And we saw an otter!

Changi Creek mangroves one month after the oil spill

One month after the 300-tonne oil spill in the East Johor Strait, there are few signs of the oil spill at the mangroves of Changi Creek.

There is some improvement compared to our last oil spill impact survey in Jan 2017, about two weeks after the oil spill. I could no longer clearly see the narrow band of oil stains on the mangrove trees. But it was alarming to see one large mangrove tree had snapped at the trunk.


Changi Beach one month after the oil spill

One month after the 300-tonne oil spill in the East Johor Strait, signs of the oil spill remains at Changi Beach near Carpark 3.

Things seem unchanged if not worse, compared to our last oil spill impact survey in Jan 2017, about two weeks after the oil spill. Attempts to deal with oiled stakes appear to have resulted in more debris on the shore.


Bleaching at Changi seagrass meadows one month after the oil spill

One month after the 300-tonne oil spill in the East Johor Strait, widespread bleaching is seen in small seagrass meadows near Changi Point Ferry Terminal.

On the high shore, oil has accumulated in a large depression in the sand. The situation appears a little worse, compared to our last oil spill impact survey in Jan 2017, about two weeks after the oil spill.
