An ocean time machine – Conservation & Science. The ocean keeps scrupulous records of its past: The comings and goings of myriad creatures, the evolving conditions they lived in, even details of who ate what.
“The ocean has a memory. We just have to tap into it,” says Kyle Van Houtan, the Aquarium’s science director. Consider the secrets we might glean from studying a single blade of algae – commonly known as seaweed. An ocean time machine – Conservation & Science. Confervae.

An international team of scientists is on a mission to give every living species on earth a unique DNA “barcode” so that they can be easily identified.
It’s an intensely ambitious project, and indexing what lives deep beneath the waves is its most challenging—and costly—vector. The initiative began in 2003 when University of Guelph scientist Paul Hebert proposed that small snippets of genetic information could be used to classify species of animals, fungi, and plants. To produce a barcode, scientists sequence a section of an animal’s DNA and give it a unique identifier. The idea is that the chosen segment of DNA is the same for all animals in a species, so comparing barcodes can identify animals when morphology—looking at physical characteristics—isn’t enough. SeaWeeds. Seaweeds are a fascinating and diverse group of organisms living in the earth's oceans.
You can find them attached to rocks in the intertidal zone, washed up on the beach, in giant underwater forests, and floating on the ocean's surface. They can be very tiny, or quite large, growing up to 30 metres long! Although they have many plant-like features seaweeds are not true vascular plants; they are algae. Algae are part of the Kingdom Protista, which means that they are neither plants nor animals. Biggest algae bloom in history hits Lake Erie - and it is large enough to cover New York City. Bloom that covered Lake Erie surpassed record-setting outbreak in 2011Scum covered an area the size of New York CityAlgae stayed away from shoreline, sparing boats and plants By Associated Press and Stacy Liberatore For Dailymail.com Published: 17:27 GMT, 11 November 2015 | Updated: 19:32 GMT, 11 November 2015 A massive algae bloom on Lake Erie has reached historic proportions - and is big enough to cover New York City.
The National Oceanic and Atmospheric Administration announced today that, with the help of heavy rains, this year's bloom was able to take the spot as largest algae bloom in recorded history. The last record breaking algae outbreak, which stretched from Toledo to Cleveland, made headlines in 2011. Scroll down for video The vast algae bloom that spread across Lake Erie this summer was the largest on record and left behind a thick, paint-like scum that covered an area roughly the size of New York City, government scientists have revealed.

Taylor, US National Oceanic & Atmospheric Administration. H. G. Aquatic Invasives Home. One of the greatest threats to the health of North America's Great Lakes is invasion by exotic species, several of which already have had catastrophic impacts on property values, the fisheries, shipping, and tourism industries, and continue to threaten the survival of native species and wetland ecosystems.
This bi-national thematic collections network of >20 institutions from eight states and Canada will digitize 1.73 million historical specimens representing 2,550 species of exotic fish, clams, snails, mussels, algae, plants, and their look-alikes documented to occur in the Great Lakes Basin. Modelling the biogeography of Antarctic phytoplankton - ePIC. Marine pelagic diatoms are coined to be strong drivers of the Southern Ocean silicate pump.
Their growth and sinking dynamics substantially affect silicate supply in lower latitude surface water masses of the world ocean. We have explored the use of species distribution modeling (SDM) to investigate the potential responses of a few key diatom species to climate change. These models describe the response of a species to its environment by combining occurrence and environmental data using statistical or machine learning approaches. Subsequently, the species’ potential distribution is mapped by projecting the model on gridded environmental layers, also for future scenarios. This methodology became a standard approach in biogeography as well as conservation and climate change science, though with a strong bias towards terrestrial organisms. A mini-mesh plant: Red Algae.
