Lots of animals (frogs, seashells, slugs, small fish, birds etc etc) 2) How would you define an intertidal salt marsh? The surface of a salt marsh is under high water at high tide and dry at low tide. A network of creeks that differ and are affected by movement of the tide. 3) Who is euryhaline and why is that important? Atlantic Stingray and Bull Shark, it’s important because in salt marshes the salinity varies. 4) Name 3 marsh skills you hope to learn in this unit. Pull a seine net Learn how to use a core sampler ID different animals. 5) What is the Funky Junk Contest? Goals? Details? date/time/location? It’s where you build a structure and you get judged based on your story and data and structure. Oct. 18th 2024. Watson 2203. 6) Name 2 marsh producers, 2 first order consumers, 2 second level consumers and 2 tertiary consumers. Pro - Plankton and grass PC. - periwinkle and grass shrimp, worms SC - Blue crab, terrapin. TC - Otter, crab 7) When did these salt marshes begin to form? Describe a typical barrier island system. At the end of the Pleistoecens epoch, glaciers started to melt into the sea and the sea level begin to rise. B.I - When sea level comes up, they protect from erosion and storms, They also move when storms are occurring. 8) What is special about the Fort Fisher Basin?

And he lived there for 17 years. 10) What are 4 elevation zones within the marsh? Mudflats Pioneer zone. Lower marsh Upper marsh 11) What is the importance of Smooth Cordgrass? Why are different plant species found in different elevations? They are very adaptable to different marsh zones and bases of all food web. Sea Pickle, Smooth Cordgrass, Black Needlerush 12) What are the 3 main benefits of oysters? What is a keystone species? Keystone species - a species that tells you the health of that location. Oysters- Filter feeders Everything eats oysters Fish habitat 13) How have we degraded salt marshes? Over harvesting of animals, and drinking water, pollution, building along wetlands, etc. End of Day 1- now meet with Mr. Bishop about science fair or work on next set of questions 14) How are HABs related to excess nutrients in the coastal waters? When a river lets out into the ocean, the river has lots of nutrients in it which makes dead zones.. 15) What data would you like to study after the field trip? Collect and view microorganisms using a microscope. 16) What are 3 critical early stage organisms that spend time in the estuary? White shrimp - March through July Gag Grouper - May and June Red Drum 17) Which 3 states along the East Coast of NA have the most salt marsh? N.C, S.C, and Georgia 18) What is the relationship between the periwinkle snail and the marsh cordgrass? Curdation 19) What is a semi-diurnal tide? What is the tide level when we visit at 11am October 1t, 2024? Means they experience two high tides and two low tides each day. It’s going down into a low tide, so about 3 ft above average sea level. 20) What is pluff mud? Why does it smell? Who can live in it? It smells like eggs because bacteria is living in a place with no oxygen. Clams, fiddler crabs, and small worms can live in pluff mud. 21) What is the difference between a trophic pyramid and a food chain?

There would be an overpopulation problem with the minions 23) What are the major differences between bony fish and cartilaginous fish? Name 2 examples of each. Way less of cartilaginous fish and way more bony fish There weight is dramatically different. 24) What are some differences between the bony fish on slide 16 & 17? Same as ^^^^ 25) What are the crabs pictured on slide 18? What zones do they live in? Horseshoe Crab, Blue Crab, Hermit Crab etc. 1. Phylum Anthophyta- Flowering plants (Smooth Cordgrass, Salicornia, Sea-oxeye Daisy, etc) 2. Phylum Arthropoda- crabs, shrimp 3. Phylum Chordata- fish, dolphins, turtles, snakes, raccoons, birds 4. Phylum Annelida- many worm species 5. Phylum Mollusca- mussel, oyster, periwinkle
