Since most plankton is smaller than we can see, they must be looked at using a microscope. They are usually strained from the water using fine mesh nets or sieves with tiny holes. Typical plankton nets have a round opening and look like a funnel that leads into a collection bucket at the end of the net. The nets are
One of the simplest biological samplers, zooplankton nets are made in a wide variety of styles and sizes. The two nets in the MARMAP Bongo vertical-haul net system explained here each have a mouth diameter of about 25 cm.
What is it and why do we use it?
An Acoustic Doppler Current Profiler, or Acoustic Doppler Profiler, is often referred to with the acronym ADCP. Scientists use the instrument to measure how fast water is moving across an entire water column. An ADCP anchored to the seafloor can measure current speed not just at the bottom, but also at
Elizabeth Eubanks M.Ed (working with Angela Gilmour, Anne Jensen, Danielle Dickson, Leslie Pierce, and Rachel Potter) connected with PolarTREC and NOAA TAS. This lesson is inspired by the need to share the importance of the Bowhead Whale in relation to the culture of arctic people. It is a portion of an entire collaborative unit to be utilized between
Dayton's News Program, Fox 45 in the Morning, talks with teacher Chantelle Rose directly from the Arctic about her oceanographic PolarTREC expedition and follow-up involvement with the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
Students chose a research project, from one of seven suggested projects, to complete in class with a partner. Upon completion they will present their information to the class.
Objectives
Students will present a scientifically accurate project on a topic related to the PolarTREC Winter Sampling expedition.
Lesson Preparation
Introduce students to the PolarTREC website. Any expedition could be selected
Storyteller Films presents the scientific efforts to understand and detect the movement of King Crab from Deep to shallow waters off the continental shelf of Antarctica. The film was made by the Palmer and Oden 2010/2011 expeditions. The crabs are an invasive species that may have large effects on this diverse marine ecosystem. The film ha a comical flair though
Local news interviews PolarTREC teacher Nell Herrmann about her expedition to Palmer Station, Antarctica. The take a visit to her classroom as well. Video and written article are included.
Do you wonder what Earth's Polar Regions are like? Where do polar bears live? Where do penguins swim? Why does the Sun never shine in winter in the Arctic? Why does aurora occur near the Earth’s Poles? How big are the Earth’s ice caps, and are they changing? The Earth’s Polar Regions are hosts to unique phenomena and ecosystems –
