Our motley crew - last day

Me, trying to look smart, and wondering whether we finally did the DO lab right...

The pool. We took samples from here, and also swam here after our first trip around the island...

The dock, we spent a lot of time here.

Kelly, Katie, Rachel, Chris, Ananda

The classroom, we spent an equal amount of time here as at the dock...

These memories will be with me forever...I don't think I will ever forget this trip.

Photosynthesis

So, photosynthesis creates sugar for plants to use for energy, it also produces oxygen. So, in this lab we experimented with 5 variables to test to see what sort of light produces the most oxygen. These are our results.

Variable Change %change
No light 1.2 to 1.2 0%
White 1.1 to 2.1 91%
Blue 1.4 to 3.7 164%
Red 1.6 to 3.0 88%
Green 1.0 to 1.0 0%

So, there are 2 light sources that did not promote any light: no light and green light.

Oxygen was produced in the experiment, which was our main goal. Success!

1. No light and green light had 0% change
2. Blue light made the most oxygen - similar to the depths of water.
3. White light had less photosynthesis occurring than blue light

• With no light - photosynthesis requires light to occur
• Green light - plant was green so its light is reflected by the green in the chloroplasts so the algae could not use the light to split the oxygen molecules
• Our error was considered to be our lack of massing the algae samples.
  

Motion in the Ocean

Waves crash when molecules underwater hit a surface and the molecules on top keep moving because their molecular force is faster. Because of this motion, tides - high tide and low tide - are characterized by the actions of the Moon and the Sun. As the moon moves closer, the water moves outwards, as the Moon moves further away, and the Sun moves closer, the water moves further away.

Water is also characterized by currents, this is caused by water hitting land, or, reflection. Shallow currents are used by ships to sail the world. Global circulation occurs with deep currents.

With northern winds, the circulation of water occurs in a clockwise motion. With southern winds, the circulation of water occurs counterclockwise.

Some more examples of tides are heap tides - these are smaller tides as opposed to spring tides - which are larger.

In relation to refraction, there is also diffraction. Refraction occurs with bent waves, which is the type we normally see. Diffraction occurs when the water passes through 2 objects, like the islands we created on our wave simulator. Reflection is the action when waves hit a surface and bounce off directly.

Invertebrate

What is an invertebrate?

• Any animal without a backbone
  

What percentage of all marine life are invertebrates?

• >90%
  

How many key phylums of invertebrates are there?

• 8
  

Porifera:

• Sponges
• Simple multi-cellular organisms with no true tissue layers or organs.
  
• Sessile/non-moving.
• Pore bearing.
• Filter feeders.
  

Cnidaria:

• Corals, Anemones, Jellyfish, Hydroids
• Radial symmetry
• Polyp/Medusa stages
• Nematocysts
• Nettle cells
• Carnivorous
• Jellyfish eat 10x their body weight, daily
• Nerve net
  

Ctenophora:

• Comb jellies
• Lacks stinging cells and possesses comb like cilia
• Coloblasts
• 95% water
• Effective predators
  

Platyhelminthes:

• Flatworms
• Slow moving worms
• Size can range from 1-5 inches
• Can be confused with nudibranchs
• Nudibranchs - shell-less snails
• Flattened and leaf like
• Bilateral symmetry
• 3 cell layers
• Brightly colored
• Mostly carnivorous
  

Annelida:

• Segmented worms, Fire worms, Feather Dusters, Tube worms
• Segments each contain the same organs
• Share a common gut, nervous system, and circulatory system
• Septa separate segments internally
• Annuli separate segments externally
  

Mollusca:

• Snails, Slugs, Squid, Octopus, Clams, Oysters, Chitons
• All have mantle, shell, and muscular foot
• 2nd most abundant marine invertebrate phylum
• Octopus and squids have a siphon as opposed to a muscular foot for movement
  

Arthropoda:

• Shrimp, Lobster, Crabs, Barnacles, Horseshoe Crab
• "Jointed foot"
• All members body plan made up of: head, thorax, and abdomen
• Exoskeleton
• Segmented bodies
• Pairs of legs
• Horseshoe Crabs have blue blood
  

Echinodermata:

• Brittle stars, Basket stars, Sea Urchins, Sand dollars, Sea Stars, Sea Cucumber
• All echinoderms are marine organisms
• Hard internal skeleton covered by a think skin and tube feet
• 5 point body plan
• Radial symmetry
• Water vascular system
• Regenerative capabilities
  

Plankton

What is a plankton?

• A plankton is any organism that moves with the current
  

What are two types of plankton?

• phyto: plant like plankton
• zoo: animal like plankton
  

Is a lion's mane jellyfish a type of plankton?

• The lion's mane jellyfish is the largest plankton, it is classified as such because it has to swim with the current
  

Meroplankton v Heroplankton

• Mero: lives part of its life as a plankton - sea stars, fish, crabs
• Hero: lives it's entire life as a plankton - zooplankton, phytoplankton
  

Where do you find phytoplankton?

• In the neuston zone - this is an area in the water that is at least 3ft from the surface
  

Where do you find zooplankton?

• Through the Diel migration pattern - this is the pattern that some marine animals follow by going from the bottom of the ocean to the top at night.
  

How do plankton stay afloat?

• using: cilia, flagella, buoyancy bubble, oil, spines, long legs
  

How much oxygen does plankton create?

• Plankton's create at least 70% of the Earth's oxygen, as opposed to the 30% that plants do
  

Biodiversity

http://www.wordle.net/show/wrdl/3712489/Biodiversity

That link will take you to a word cloud (again):

Here I will (again) define the terms for you.

Percent Error: take more samples, use more transect lines, (Final-Initial/Final)*100

Quadrat: a portable frame, with an internal grid. Used to mark out the number of species in a small area/habitat

Shannon Index: count species

Richness: count species

Monera: a former taxonomic group within the domain Prokaryota - bacteria, archaebacteria, and blue-green algae

Protist: free living or colonial organisms with diverse nutritional and reproductive modes

Fungi: any group of unicellular or multicellular spore producing organisms feeding on organic matter; including molds, yeast, mushrooms, toadstools

Plant:the taxonomic kingdom comprising of all living or extinct plants

Animal: the taxonomic kingdom comprising of all living or extinct animals

Population: all the inhabitants of an area

Density: the degree of compactness of the species

This is the simplest way to understand the Biodiversity of organisms.
