Let's talk #zooplankton nets. Why, on a large ship, do we use a net with very small diameter (0.4 m), but it is long (2 m)? Efficiency! These nets filter better, while not collecting *too much. #Eutrophic systems like #LakeErie clog nets with algae, so less volume is better. We target sizes using different Nitex meshes, most often 63 or 153 μm in the #GreatLakes. To measure volume, we use a flow meter mounted just off-center in the net mouth (know why?). #Science

Neue #AWI-Studie zeigt: Der #Klimawandel verändert die Wanderung von #Zooplankton und lässt die winzigen Tiere künftig länger in der Tiefe der Ozeane bleiben.

Arktischer Ozean: Klimawandel gefährdet Nahrungskette

Der Klimawandel bedroht neuen Untersuchungen zufolge das gesamte Ökosystem in der Arktis. Forscher warnen vor Folgen für alle Meeresbewohner - vom Zooplankton bis hin zu Robben und Eisbären. Von J. Meier-Wendtke.

Weekend #Plankton #Factoid 🦐🦠

One #Hakai video I just posted on was on Diel Vertical Migration of #zooplankton (also motile #phytoplankton). DVM is the largest movement on biomass on the planet, occurring every morning and evening in #lakes and #oceans, as much as 100s of meters (impressive for something a couple mm long). They swim up to feed on algae at night and to avoid visual predators. They also save on energy because deeper cooler water means slower metabolism.

Related to my FLIP post, this ship was vital to study of Langmuir Circulation. Wind on water results in alternating spirals forming sequential zones of convergence downwelling and divergence upwelling. Bubbles & buoyant flotsam collect in downwelling zones forming distinctive "windrows". The diffuse upwelling zone aggregates sinking / swimming #zooplankton (depends on swimming speed) targetting food particles in the current. #Oceanography

Seismic blasting is deadly for marine life and can impact all levels of the food chain from its very foundations, killing #zooplankton more than a kilometre away, to deafening #whales.

Sunday #Plankton #Factoid 🦐🦠

An important yet not well understood component of the plankton are #viruses. They are ubiquitous in all aquatic systems, infecting #zooplankton, #phytoplankton, #microbes & more. They are vital for carbon flux, algal bloom #lysis (cell death), which can lead to toxin release. As you might expect, because of their small size (often >60 nm) they are hard to sample and measure.

Time for updated #introduction with the new influx of users from dysfunctional Twitter.

I'm a #GreatLakes Research Scientist working for Fisheries and Oceans #Canada (#DFO) based out of the Canada Centre for Inland Waters in Burlington. My group is responsible for lower trophic #FoodWebs (microbes, phytoplankton, #zooplankton and diets of forage #fishes). This supports recreational & commercial fisheries and ecosystem health in the lakes.

While many #zooplankton have eye-spots of pigment, and do respond to light cues (thus diel vertical migration), some are weirdly advanced. A 🇨🇦 study found that predatory athecate #dinflagellate called Warnowiids have an almost animal-like #eye structure called an ocelloid used to track prey. The structure has organelles formed from several cell structures and endosymbionts, which form a type of retina, cornea, and lens. 👁

With invention of the microscope in the 1600s, one of the first #zooplankton species described were #rotifers by John Harris and Antonie van Leuwenhoek. Named "wheeled animalcules" because of their distinctive ciliated corona used for feeding. Ubiquitous in most #freshwater systems. Some can be dried out and revived, and though they are dioecious, many are parthenogenic (female clones). Very important to aquatic #FoodWebs.

The #DFO #ECCC #CSMI 🇨🇦🇺🇸 #LakeOntario cruise is moving along nicely on the CCGS #Limnos. The stations off Oswego, NY take a little longer because these are the deepwater stations for Lake Ontario with max depth of 244 meters (802 feet). These are stations where we will most likely catch Mysis diluviana, an important #FoodWebs #zooplankton. We should be done the US waters stations by end of today and move to the north shore to complete the survey. #CooperativeScience #Plankton #Chemistry

The term #Meroplankton refers to an organism that spends only part of its life cycle in the water column drifting as plankton. An organism which spends its entire life cycle is termed #Holoplankton. Meroplankton include juveniles of many benthic groups: starfish, barnacles, sea urchins, crabs, and even fishes. They often have very distinctive shapes. During certain times of year, they can dominate the #zooplankton by density, especially in coastal regions.
