Sunny day at Terumbu Semakau

On Labour Day holiday, the intrepid team surveyed Terumbu Semakau, a patch reef off Semakau Landfill. The abundance of hard corals have dropped as several ones did not survive the coral bleaching period last year. Nevertheless, there's still good growths of corals at certain stretches. We also saw both the Fluted and Burrowing Giant clams, a special sea cucumber and some pretty sea slugs!

Sea fan garden at Changi

Beyond the murky waters of Changi, one would be able to catch a glimpse of the colourful sea fan garden during super low spring tide! On 30 April 2017, I visited a stretch of Changi that I've not surveyed for years.

Other than having the joy of finding high abundance of sea fans, we also enjoyed a lovely sunrise, finds of commensals on the sea fans and other interesting critters such as the Sea Apple sea cucumber and the Armored sea cucumber.

New snail find at Kusu Island!

We visited Kusu Island on 29 April 2017 and checked out the reefs. Am glad to see many of the corals survived the bleaching period last year and that the reef is still thick at Kusu.

Many fantastic finds such as featherstars, many heart urchins emerging from the sand at the lagoon and my first sighting of the Marlinspike Auger Snail (Oxymeris maculata)!

First predawn at Tanah Merah shore

It's our first predawn low tide trip this year and on 28 April 2017 we visited Tanah Merah shore. The first exciting find of the trip would be the stonefish!

I later also chanced upon a Knobbly sea star. The corals are still ok though some are dying or dead due to the previous round of coral bleaching. The seagrasses invaded upstream of the canal where we also found tiny white sea urchins and other interesting finds.

Higher low tide at Big Sister's Island

On 12 Feb 2017, we visited Big Sister's Island during an evening low tide. The tide didn't go down as predicted and we were stranded on the high shores. Nevertheless, the team managed to find some exciting critters both beneath rocks and above ground.


Windy at Cyrene Reef

Two weeks after Chinese New Year, we are out on another evening tide to check out one of our favourite shores: Cyrene Reef!

Cyrene Reef is ringed by petrochemical plants on Jurong Island and Pulau Bukom. It is also right next to the container terminals on  Pasir Panjang. Cyrene Reef has one of the best seagrass meadows in Singapore and its seagrasses are home to lots of marine life!

It was very windy on this trip but we also get to enjoy a rainbow that emerged from the direction of mainland.

CNY Day 3: Seringat-Kias

It's CNY Day 3 and we are at the reclaimed shores of Seringat-Kias, which is also connected to Lazarus Island.

We enjoyed the pinkish sunset after the rain that poured when we arrived! There's a bloom of the Sea lettuce (Ulva sp.) seaweed that covered the intertidal stretches of the shore.

CNY Day 2: Terumbu Selegi

After 6 years, we are finally back on Terumbu Selegi on CNY Day 2!

Terumbu Selegi is a submerged reef in the middle of nowhere. The nearest islands would be Sentosa, St John's Island and Sisters' Islands.

CNY Day 1: Semakau South

It's the Chinese New Year again! And that also signifies another round of low tide adventures. :)

This super tiny snail that is only around 5mm or less was found by none other than our bionic Chay Hoon! The scientific name for this fellow is Cystiscus minutissimus. And it's also apt for the CNY season given that it is all orange.

Coral bleaching at Terumbu Pempang Laut

On 6 Aug 2016, we visited Terumbu Pempang Laut for a coral bleaching check. However there are not many corals on this shore as compared to the rest.

We estimate about 20-30% of the hard corals are bleaching. About 20-40% of the leathery soft corals were bleaching. We estimate 20-30% of the corals have died recently.

Coral bleaching at Semakau East

On 23 Jul 2016, we visited Semakau East to check out the coral bleaching situation.

It seems that the reef is doing badly. We estimate about 70% of the hard corals and 40% of the leathery soft corals are bleaching. We estimate 5-10% of the corals have died recently.

Coral Bleaching in Terumbu Semakau

Our final survey for this season of low spring tide would be to check out the coral bleaching at Terumbu Semakau, a patch reef off Semakau Landfill.

How are the corals doing? Unfortunately, they are not doing well.

Baby Knobblies at Pulau Sekudu

With permissions from National Parks Board, we are back at Pulau Sekudu to do our annual survey. Otherwise, this island is actually out of bounds.

We had the best sunrise out of the 3 days we were out thus far! I must say this shot is definitely postcard-worthy. Thank God once again for great weather. :)

My favourites on East Coast's reclaimed shores

Despite most people's perception that there's not much marine life in Singapore, we do have lots of shores to explore during low tide. And I'm back here checking out two stretches of East Coast after two years since 2014. How are they doing?

Once again, we ended our survey of 2 shores with a beautiful glow from sunrise. Prior to this, we spent some time checking two different stretches.

Predawn at Chek Jawa coral rubble

I'm back at Chek Jawa, one of the two seashores that started my passion in marine life (the other is Tanjong Rimau, Sentosa). It's like visiting your friend that has been there all along through different seasons. That applies to both the shore and myself. We were able to visit this shore with permission from Nparks.

The team soaked in the magnificent presence of the glows from the sunrise after we ended the trip. Yes, we arrived at Ubin before 3am to do a predawn survey and ended at dawn.

Back at Pulau Tekukor with turtle find

After 6 years, I finally set foot at Pulau Tekukor again! My last survey here was in 2010.
 

The natural rocky coastline is a prominent feature of this untouched island that sits right across Sentosa and St John's Island.

Coral bleaching at Cyrene Reef

Most of the time,we will be exploring the seagrass and sandy areas of Cyrene Reef as they are thick with critters. On a super low tide, we decided to dedicate a slot for Cyrene Reef to look at the reef edge. However, it coincided with the coral bleaching period and it became a survey to monitor the extent of bleaching.

It's heartbreaking to see many of the corals bleaching. About 80% of the hard and soft corals appear stressed as they lose their coloration.

Spongey comeback at Beting Bronok

Beting Bronok (BB) is one of our last northern reefs that is home to a wide variety of marine life that we don't see on our mainland shores. We only visit BB once a year to do our annual survey and noticed over the years that the reef is deteriorating.

BB is located off the north of Pulau Tekong and it is only exposed at a good low spring tide. Just right across the channel (Eastern Johor Straits) would be Pengarang, Johor. Today, we noticed that the sponges are making a comeback! You can see good growths of the colourful sponges in this landscape shot.

Back at Changi's echinoderm haven

One of the first few shores that shore lovers would visit definitely includes Changi Beach.

After one year, I'm back to take a look at how it is doing and we agreed it has changed. Nevertheless, it is still an echinoderm haven.

Coral bleaching check at Tanah Merah

I have been visiting the reefs off Tanah Merah since 2009 and it continues to be the best mainland coral reef despite being a reclaimed shore. It has suffered from the oil spill and coral bleaching period in 2010 and after about 6 years we are facing yet another coral bleaching period this year.

How are the corals doing? From this photo, you can see that some species are more affected than others.
