[Conference Announcement] International Conference on Plastics in the Marine Environment 2018

Globally, some eight million tonnes of plastic is dumped into the ocean every year, killing marine life and entering the human food chain. Five Asian nations account for 60% of the waste entering our oceans. The ubiquitous spread of plastic waste into every part of the marine environment has captured the attention of academics, industries, environmentalists, and the public. Plastic debris and animals killed by the ingestion of plastic capture the daily struggle of the world’s ocean ecosystems. The massive scale of this problem threatens our food security and sustainability.

[New Equipment] Diving PAM II

We are excited to announce the acquisition of a new Pulse Amplitude Modulation Unit, Diving PAM II, available for all registered users!

There will be a demonstration of the equipment on Tuesday, 30 October 2018 at 2.30pm.

The Diving PAM II is an underwater chlorophyll fluorometer, designed for the examination of photosynthesis in water up to 50m. It measures chlorophyll A fluorescence in photosystem II underwater plants such as sea grasses, macroalgae, and zooxanthellae in corals.

[Seminar] Pteropods and Lumpfishes

Pteropods are planktonic gastropods that live in the water column throughout oceans worldwide. They show limited acclimation responses to the effects of ocean acidification (OA), with dissolution of their shell observed in individuals exposed future acidity levels. However, we also need to study their long term adaptive potential to cope with incremental changes in acidity.

[New Equipment] FlowCam 8000

St John’s Island National Marine Laboratory is excited to announce the availability of the FlowCam 8000 for all registered users!

There will be a demonstration on the equipment on Tuesday, 25 September 2018 at 2.30pm.

The FlowCam is a dynamic liquid imaging particle analyser that rapidly takes images of magnified particles flowing through a fluidic system. This is then followed by the use of an image analysis software to characterise and identify the particles.

International Polychaete Day Feature Series IV

From local biodiversity to ecologically important tubeworms and their larval culture, we focused on various aspects of polychaete biology research conducted by scientists at the St John’s Island Marine Laboratory (SJINML). As we wrap up the International Polychaete Day special series, we share one more exciting research ― polychaetes found from deep sea biodiversity expeditions undertaken by scientists at the SJINML.

International Polychaete Day Feature Series III

This week’s feature on polychaete research at the St John’s Island Marine Laboratory (SJINML) continues on the subject of tubeworms but with a twist, literally and figuratively ― we introduce the biofouling spiral tubeworms known as spirorbins.

Tubeworms actually refer to polychaetes from the family Serpulidae, which include the species Spirobranchus kraussii from last week’s Feature Series II and the spirorbins that we will talk about today. Last week, we shared about their special ability to build hard calcareous tubes that encase their soft bodies. The tubes are important protective structures against predators and also desiccation when the tubeworms are out of water, for example during low tides.
