[Seminar] Microplastic Debris in Deep-Sea Canyon, Estuarine, and Shoreline Sediments

Events, Highlights, Seminar /

Recent calculations estimate that there are currently 5.25 trillion plastic particles afloat in the world’s oceans. Many of these are microplastics. The purpose of this ongoing study is to investigate how microplastics are distributed in two different marine environments: deep-sea canyons, and nearshore estuaries. To discover whether microplastics are concentrated in these environments, I analyzed microplastics in sediments from Norfolk Canyon and the adjacent continental slope; and the Coos Bay Estuary and the adjacent continental shelf. Sediment samples were taken with a box core and a ponger grab. I submerged sediment in saturated solutions of sodium iodide for floatation. I removed the supernatant to extract plastics through optical microscopy.

[Seminar] Perspectives from the Canadian Environmental Microplastics Facility

Events, Highlights, Seminar /

Microplastics (<5mm) have been found in nearly all environments on earth and studies have been documented plastic ingestion by a wide range of marine biota. Rhiannon will be covering several topics surrounding this emerging environmental contaminant including sources, fate and effects of microplastics and what Ocean Wise is doing to research this environmental contaminant.

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

Events, Highlights, News Feed /

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

Highlights /

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

Events, Highlights, News Feed, Seminar /

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.
