Module 12: Continental Shelf Communities – Part 2

March 3, 2015 PowerPoint  Honors Marine Biology Module 12 Continential Shelf Part 2

In most of the cold temperate areas of the world, hard-bottom shelf substrates are inhabited by large, brown seaweeds known as kelp. Kelp can grow quite tall (up to 30 meters) compared to other seaweeds. Kelp Beds create a third dimension to the hard-bottom communities, in the same way that trees create canopy structures in forests.

In Kelp Forests a canopy is formed when the kelp is tall enough to stretch from the bottom of the subtidal community all the way up to the surface. As a result, most of the kelp is underneath the water, but some of it is on top of the water as well. When kelps are not tall enough to reach the surface and form a canopy, the community they form is called a kelp forest.

If you have NetFlix watch Mike Rowe in Dirty Jobs as Mike gets dirty harvesting kelp to feed abalone. NetFlix:  Dirty Jobs Season 3 Episode 11

Module 12: Continental Shelf Communities – Part One

February 24, 2015 PowerPoint Honors Marine Biology Module 12 Continental Shelf Communities Feb 21 2013

Congratulations to Cameryn for winning the class challenge!  Thanks to all who participated.

Camyern Bowers The continental shelf is a gently sloping area, beginning at a point near land, just below the low-tide mark.  It continues out to the shelf break, which is the outer edge of the continental shelf.  This area contains abundant quantities of life. Vast fishing areas are found here.  Coral Reef communities are located on the continental shelf. Let’s look at life on the bottom of the continental shelf. Using scuba diving equipment and underwater submersibles, scientists are beginning to learn more about the vast resources in this area. Oil and mineral deposits are found here, and nations depend upon many of the resources in this underwater zone. Review the following videos.

Homework

  1. Take Module 11 test
  2. Read Module 12 to page 297
  3. OYO: 12.1 – 12.9

Module 11: Coral Reefs

February 17, 2015 PowerPoint  Honors Marine Biology Module 11 Coral Reefs part 1

Coral Reefs are home to an amazing assortment of organisms and are truly the underwater equivalent of a diverse rain forest.  Coral reef communities are found in the tropical climates of the world because reef-building corals need warm temperature in order to survive.  They are found between the Tropic of Cancer and Tropic of Capricorn latitudes. This “band” around the earth receives a much larger portion of sunlight throughout the year than the rest of the world and has overall warmer climates.

Module 10: Estuary Communities – Part 2

February 10, 2015  PowerPoint Honors Marine Biology Modular 10 Estuary Communities Part 2

Congratulations goes to Ethan for demonstration the best magic trick.  Thank you to all who participated!

Sarasota Bay is a beautiful 56-mile long coastal lagoon comprised of one large bay segment (Big Sarasota Bay) and several smaller embayments including Palma Sola Bay in the north and a series of three embayments (Roberts Bay, Little Sarasota Bay, and Blackburn Bay) to the south. The Bay has four inlets or passes (Venice Inlet, Big Sarasota Pass, New Pass and Longboat Pass).

Map of Sarasota Bay EstuaryEstuaries are semi-enclosed areas, such as bays and lagoons, where freshwater mixes with salt water from the sea. Teeming with life, our nation’s estuaries provide vital habitats for 80 percent of the world’s fish and shellfish species. Estuaries are an essential resource creating more food per acre than the richest farmland.

Estuary habitats are divided into three major habitats:

  1. Wetlands  (Salt Marshes and Mangrove Forests)
  2. Mudflats: Wide expanses of an estuary that are exposed during low tide.
  3. Channels: Water is present both during high and low tides.

The three types of organisms that can endure estuary conditions are classified as:

  1. Euryhaline:  Species that can tolerate a wide range of salinities.  There are many species which have life cycle requiring tolerance to both fresh water and seawater environments such as salmon and herring.
  2. Stenohaline:  Species that can tolerate a narrow range of salinities and describes an organism, usually fish, that cannot handle a wide fluctuation in the salt content of water.
  3. Brackish:  Water that is less salty than seawater but saltier than fresh water. Brackish water is the natural habitat for a diverse group of aquatic animals that have adapted to the environment.Many animals that thrive in brackish waters can cause health problems to humans who eat them.

Class members gave excellent oral presentations of estuaries from around the world.

1.   Drowned River Valleys (sometimes called coastal plain estuaries)

2.   Bar Build Estuary (barrier island)  (Sarasota Bay is an example)

3.   Fjords

4.   River Delta Estuary

5.   Tectonic Estuary (Basin that was filled with water)

Those students who did not give their presentations, be prepared to do so at our next class on February 17.

Homework:

  • Take Module 10 Test
  • Begin reading Module 11 on Coral Reefs to page 269.
  • OYO:  11.1 to 11.6
  • Study guide:  define a-c  2-13
  • Class Challenge:  Best Joke
  • No Class Quiz

Have a good week! – Mrs. S

We have discussed estuaries throughout the year and you should be very familiar with them.  In this week’s class we identified the five types of estuaries and showed examples of them from around the world.   These estuaries are believed to have been formed as a result of actions that occurred during an ice age.  

I shared with you the resources found at the Institute of Creation Science. Their website http://www.icr.org  Go to search tools and type in any aspect of science that you may need scientific data and analysis to go along with anything you are learning.

We identified 5 types of estuaries

1.Drowned River Valleys (sometimes called coastal plain estuaries)

2.Bar Build Estuary (barrier island)

3.Fjords

4.River Delta Estuary

5.Tectonic Estuary (Basin that was filled with water)

Each of you selected an estuary for your oral presentation in class on February 10. Each person will give a 3 minute presentation of:

  1. What you have learned about your type of estuary;
  2. Select an example from around the world;
  3. Then include photos of the estuary, birds, fish, commercial development or any other aspect of the area that you learned about.

Homework:

  • Field Trip next week – Birding Feb 3
  • Estuary Presentation on February 10
  • Finish reading Module 10
  • Answer OYO and Study Guide

Last week we looked at rocky intertidal zones.  This week we will examine the sandy and Muddy intertidal zones.  They have no Rocks! These soft-bottom areas are in protected stretches of coastline or in areas where loose sediments have accumulated over time.

Sandy bottom Intertidal zone

Soft bottom ecosystems are  identified when the sediments are so loose that organisms can burrow into them. When the excess sediments accumulate, the wave action is usually not too severe; therefore different organisms inhabit these communities as compared to the organisms of the rocky intertidal. A community such as this is influenced by two major parameters:

  1.  Water movement
  2.  Sediment size and type

The substrate of a soft-bottom ecosystem is often unstable and is deposited based upon the amount of waves and currents that push it around.  Grains of quartz, volcanic sand and tiny bits of animal skeletons can all make up a soft-bottom community.

Experiment 9.1:  Examination of Intertidal Zone:  Mud Core Sample from  Siesta Key (North Bridge).  Complete lab and drawing.

Experiment 9.B:  Environmental Management Coastal Erosion Engineering Presentation 

Lido Beach beach re-nourishment: Sand was brought in from another area. As engineers it is your responsibility to offer design recommendations to the Sarasota County Commission for the retention of the sand.  Also consider the species  that live in the environment along the beach front.  (see PowerPoint) Write a good paragraph with well thought design suggestions. Include a diagram.
