I was so hyped to see my first blue bottle outside of a module!! In real life!! Got myself to touch it for a second, carefully avoiding its tentacles so as not to get stung #marenvs19

[Keri Zhang @kerimarinesci]

Can't believe we saw this! If you look closely you can see blood in the water 😲 - turns out sharks are abundant in Fingal Bay, so our guess is that they were probably feeding near where we walked! #marenvs19

This is crazy to see - sea levels can be expected to rise by 1 meter by 2100, one factor being glacial melt #marenvs19

[Laurie Garrett @Laurie_Garrett]

This is a roaring glacial melt, under the bridge to Kangerlussiauq, Greenland where it's 22C today and Danish officials say 12 billions tons of ice melted in 24 hours, yesterday.

More tropical depressions develop into hurricanes over warm water, so the warming caused by climate change is not making things look good #marenvs19

[National Geographic @NatGeo]

Like adding more fuel to a fire, warm water (whether heated by regular summer temperatures or greenhouse gases) make hurricanes stronger https://t.co/t4iY9sP2gl

We're eating, drinking, even breathing hella microplastics 😖 Notably, drinking bottled water adds an additional 90,000 pieces of microplastics to estimated consumption, compared to tap water's additional 4,000 - yet another reason to ditch single use plastic bottles! #marenvs19

[National Geographic @NatGeo]

It's possible that humans may be consuming anywhere from 39,000 to 52,000 microplastic particles a year https://t.co/fG2kNZ7mWH

Beyond-the-class material that engages class material - this #ecoSUB is measuring factors influencing #calving in glaciers - in class we learned how salinity & temperature affect water densities, which is at play here w melt water & salt water circulation interactions #marenvs19

[Lenique @LeniqueUNSW]

#marenvs19 Ocean acidification & climate change don’t just affect the reefs we learned about - it’s also possible we’ll be seeing way too many jellyfish

[Keri Zhang @kerimarinesci]

Let's see if this floating boom system can work away at the Great Pacific Harbage Patch! It's designed so fish won't get caught but plastic will #marenvs19

[Keri Zhang @kerimarinesci]

@HudaUNSW It's relentless 😤😆

[Keri Zhang @kerimarinesci]

Keeping hydrated throughout the day's changing tides is key if you live in the intertidal region, like this urchin crawling to water collected in this rock pool. The rock pools of the low/middle intertidal regions are teeming with urchins, you just gotta look! #marenvs19

[jennaunsw @jennaunsw]

A cool time lapse I took of a sea urchin crawling back towards the water. I’ve never seen these guys move before so this was pretty cool to watch! #marenvs19

[Keri Zhang @kerimarinesci]

Isn't this beautiful? The prey is driven against the water's surface so they're in a more compact 3D space for more efficient feeding #marenvs19

[Susan Li @susan_li117]

Cooperative feeding allows whales to help dolphins and seabirds catch prey! Amazing how much they can eat when they work together #MarEnvS19

[Keri Zhang @kerimarinesci]

Didn't delve into this in class, but thought this was so great - trace genetic material from samples of water called environmental DNA #eDNA can empower researchers to survey the vastness that is ocean life in a relatively inexpensive way! #marenvs19

[ISHInews @ishinews]

eDNA analysis is a lot like forensic work at a crime scene, says Dr. Chavez, a senior scientist at the Monterey Bay Aquarium Research Institute (MBARI). Investigators gather evidence, compare it against a suspect bank, and hope for a match.

On a ferry, I saw the turbid nutrient-rich green-blue waters of Sydney's #MiddleHarbour, where bull #sharks can be found - I understand the warnings against swimming here, you really can't see thru the murk! Shark attacks are infrequent, but always exercise precaution #marenvs19

[Grace M @gfm_downunder]

Got to see a dugong up close today! Definitely able to see that 70° angle of the jaw @Sydney_Aquarium #marenvs19

[Keri Zhang @kerimarinesci]

Not all fish stock are equally sustainable - some are endangered, so check seafood labeling for species type and where/how it's been caught, then look up if that species is being sustainably fished. This gov website is a great resource to use! #marenvs19 https://t.co/qwn1GgZ5Jq

Scientist In Mexico Creates Biodegradable Plastic From Prickly Pear Cactus via @forbes https://t.co/wdGHUYO8VJ this could have huge implications on the negative impacts that plastic places on our marine environments since this plastic can dissolve in water in days #marenvs19

[Lenique @LeniqueUNSW]

I’m Caribbean so I wanted to explore Caribbean Sea issues that relate to our class content- this article talks about the huge seaweed problem that has affected the health of sea grass beds & coral among other things #marenvs19 https://t.co/YB08FvsQfE

[Keri Zhang @kerimarinesci]

We've talked about the feasibility of solutions to marine environment issues - having government support provides the resources many projects need to be effective #marenvs19
