Presentation on theme: "The Science of Marine Biology"— Presentation transcript:
1The Science of Marine Biology Marine Biology is a general science applied to the seaStudy of Marine LifeNearly all disciplines of Biology is represented
2Oceanography – Scientific study of the physical and chemical properties of the ocean. Geological Oceanography: Study of the Sea FloorChemical Oceanography – Study of waves , tides, currents, etc.
3History of Marine Biology Stone Age – Evidence of clam bakes , ancient Harpoons and simple fish hook have been found
4Marine animals are used for food - evidence found in an Egyptian tomb where a puffer fish is depicted as poisonous but were not maritime people
5PhoeniciansFirst accomplished Western navigators. Sailed around the Mediterranean Sea, Red Sea, Eastern Atlantic Ocean, Black Sea, and Indian Ocean.Established colonies and commerce
6Minoans of Crete and Myocenean Greeks They made voyages within the Mediternean Sea.
7HomerThe Homeric poems describe events around 1200 BC and involve fairly extensive sea voyagesReferences to the sea and its mysteries abound in Greek mythology, particularly the Homeric poems "The Iliad" and "The Odyssey".However, these two sources of ancient history mostly refer to the sea as a means of transportation and food source.
9AristotleAristotle - First marine biologist. Described marine life forms and recognized fish breath by gills.
10Writings of AristotleFrom BC that specific references to marine life were recorded.Aristotle identified a variety of species including crustaceans, echinoderms, mollusks, and fish.He also recognized that cetaceans are mammals, and that marine vertebrates are either oviparous (producing eggs that hatch outside the body) or viviparous (producing eggs that hatch within the body).
11DARK AGES · Vikings explored then northern Atlantic. · Leif Eriksson - discovered “Vinland” (North America)
12What were the Dark Ages? Causes: Barbarian invasion brought down the Roman EmpireRoman Empire was already in decline militarily, economically, socially, politically476 A.D. to 800 A.D. ( Accession of Charlemagne as a the First Holy Roman EmperorTime of constant warfare, despotic chiefs and minor kings, migrations of entire nations.
13Darks Ages Cont. Much of the learning by the Romans built up Destroyed with the libraries.
15Leif Erickson (Son of Erik the Red) Father found the first European settlement On GreenlandBorn in IcelandHe was on a return trip from Norway after being converted to Christianity and sailed off of course or searched for Vinland from an Iceland trader story of seeing the shore.He landed 500 years before Columbus.Never returned after spending the winter there,.Died in Green LandEstablished a Norse Settlement in Canada at the tip of New Foundland.
17Leif’s TravelsHe landed in Vinland by mistake, Leif was blown off course to Greenland to introduce Christianity.
18Vikings The Vikings Origins Came from Scandinavia Present day Norway, Sweden, and DenmarkTerrorized EuropeAttacked from the seaTheir shipshad high prows, so they were good in heavy seashad shallow drafts, so they could quickly and easily pull onto shore for attack, then push back into water to get awayTypically carrying warriorsSome Capable of holding 300 warriorsFearsome fighters, often killing even unarmed churchmenSettlers throughout the AtlanticExplored far into the North Atlantic
19Viking s Continued Settlers throughout the Atlantic Explored far into the North AtlanticEstablished settlements on Iceland and GreenlandExplored as far as Newfoundland (Leai Ericson)At one time, controlled part of ireland, nearly all of England, Northern France (Normandy)Pattern typically was raid and terrorize first, settle laterEnd of the Viking ageEurope learned to respond quickly to Viking raidsAdoption of Christianity by the Vikings made them less hostile toward fellow ChristiansGlobal warming about this time made Viking settlements especially prosperous
20Arab Traders· Arab Traders - voyaged to East Africa, South East Asia and India·
23Christopher ColumbusRediscovered the New World 1492European Voyage
24Columbus continued…. Born: Cristo Colombo He Convinced that traveling west will open new route to Asia.Most European Rulers did not support him.Finally Ferndinand and Isabella of Spain financed him.He was a cheapskate. He promised gold to the person that first sighted land.
25Columbus continued…..Oct 12, Rodrigo De Triana sighted the island s of the Brahamas. Chris took the sighting and claim he saw a glimpse of it at nite. Sailor did not get the reward.Named the Island San Salvador
26Columbus Voyages a Disaster! Santa Maria ran aground, left 39 men strandedReturned to Spain without a new route to Asia , no spices/ valuable goods4th voyage ship rotted out below him and was stranded for a year in Jamaica.
27Columbus Reward King of Spain made him governor of Santo Domingo Ruled like a ruthless KingHe was replaced and arrested in Spain.
28Ferdinand MagellanFirst to sail around the world
29Magellan Born in Portugal Studied Mapmaking and navigation Financed (1590 ) King Charles V of Spain to circle the globe to prove that the earth was round.Studied the mistakes and discoveries of Christopher Columbus with North America and Balboa with Pacific Ocean andPanamanian Isthmus
30Magellan cont…. Fleet of five ships Oct 1520 entered the Strait of MagellanMarch 1522 anchored in GuamKilled in a local war in the PhilipinesRemaining crew completed the circumnavigation of the globe . Returned to Spain Sept 1522 under the guidance of Del cano.
32James Cook English First to make scientific observations A full time Naturalist was on board the ships3 voyages explored all the oceans.First to see the Antarctic Ice Field..He Landed in Hawaii, New Zealand, Tahiti and other Pacific Islands.
33Other FirstsUse a chronometer ( time piece) to determine his longitude and prepare accurate charts. Reshaped the European conception of the world. Collected Samples of organisms and plants Killed in a fight in Hawaii with some natives
35Darwin Continued…. Englishmen He h ad extensive interest in the study of BarnaclesSailed on the HMS Beagle for five years.Proposed the Theory of Evolution by Natural Selection and AdaptationIn 1859 , he published “On the Origin of Species”His College Professor Henslow recommended him as a Naturalist position on the Beagle.Explain how Atolls were formed.
36Darwin Continue….He collected a variety o f specimens ( birds, plants and fossils.)He did experimentation and research experiencing botany, geology, and zoology.The Galapagos islands were of prime interest. As was South America.On his return , he began to develop his theory of evolution from his writings.
37United States Exploration Voyages United States Exploring Expedition of also known as the “Wilkes ExpeditionNaturalists and Artists ( Clam diggers)The Voyage was more of projecting American influence than scientific discovery.Leader Charles Wilkes
38Wilke’s Accomplishments Charted 1,500 miles of the coast of AntarcticaConfirms Antarctica is a continent.Mapped the coast of the Pacific Northwest of North AmericaExplored 280 Islands in the South PacificCollected 2000 unknown speciesFirst international survey sponsored by the U.S.Laid the foundation for gov’t funding for scientific research
39Edward Forbes Carried out extensive dredging of the ocean floor. He dredged around Britain ,in the Aegean sea and the Mediterranean SeaAccomplishments: discovered unknown organisms.Realized that the ocean varied in depths
40Forbes Continued…..Britain, Germany, Scandinavia and France continued the study of the ocean floor.This lead to the funding of the Challenger Expedition
41ForbesHe Published two books based on his interest in the littoral zone of the oceans.The British History of Starfishes and The British History of Mollusca.
45Modern Oceanography began….. yearsOriginally organized specially to gather data on a wide range of ocean features:temperature marine lifechemistry geology of ocean floorcurrents
46Ship Construction….. British Navy provided the war ship. Converted it to a lab ship with microscopes and other scientific equipment.Naturalist : John MurrayExpedition left Portsmouth England Dec. 1872
49Lab work Salinity and other chemical variable were measured. James Buchanan determined that the white slime was a precipitate of calcium sulfate which is formed in alcohol .It was a white slime that came up in bottom deposits.
51Gas analysis ……Evaporating Gases could be trapped as was carbonic acid and analyzed by chemical titration.Allowed for the mapping of the ocean ‘s chemistry through out the worldCarbonic acid has to be analyzed soon after the sample was collected.
58Results Reported 50 volumes of Information 23 years to compile The two summary Volume devoted to the people , costumes and scenerySome of the people encountered were cannibals such as King Thacker of the Fiji Islands
60Travels of the Challenger From England traveled to the South AtlanticThen around Cap e Good Hope of AfricaThen cross the Indian Ocean.Crossed the Antarctic CircleOn to Australia and New ZealandNorth to Hawaii and around the tip of South America. To England.
61DiscoveriesThe Marianas Trench – deepest part of the ocean in the Western PacificDeepest sounding taken (Challenger Deep)37,800 feet deepFirst broad outline of the shape of the ocean basin including the rise in the Atlantic OceanMapping of the currents, and temperature4,700 new species
62Marine LabsHenri Milne Edwards and Victor Andourn - Studied the seashore at the seashore.Laid the foundation of Marine Labs.Stazione Zoological - First lab founded in Naples, Italy. 1872Founded by Anton Dohn as a private concern1st, directory, German Descend, field of Biology, Darwinist1982 –under control of the ministry ofUniversity and Scientific and Technological Research as a National Institute,Introduced the “bench’ system– space rented out to universities and governments for them to send one scientists to research with everything provided. This system established international collaboration was invented,
63Marine Biological Society of the United Kingdom founded in Plymouth, England. Marine Biological Lab at Woodshole, Massachusetts: (WHOI)· First major American marine lab. Initiated by U.S. Fish Commission. It closed! Cape Cod, Mass· Center for the world's expert in cell division.· Using polarizing light microscopy and video imagining clarifying the events of mitosis and discovering the spindle fibers .· 1980’s the first class of proteins (cyclin) that regulated the cycle of cell division· Cornerstone Institution in the Encylopedia of Life (EOL) project a global initiative to electronically document all 1.8 million named species on Earth.2nd lab opened up after another lab moved to same location from Cape Cod. Largest Independent
73John Steinbeck and Ed Ricketts Stein beck author ofGrapes of Wrath, Of Mice and Men andEast of EdenSteinbeck had an interest in Marine BiologyMet Ed Ricketts owned Pacific Grove Biological laboratory
74Steinbeck/Ricketts cont…. Lab was located near the Hopkins Marine Station and the present site of the Monterey Bay AquariumRicketts collected marine specimens and sold them to museum and universities.
75Steinbeck gave Ricketts credit for his views on humanity and the world. Ed Rciketts was a character in six books .The most famous was” Doc” in Cannery Row

91Ed Ricketts Published 1939 Publication Between Pacific Tides Comprehensive guide to sea life along the Pacific coast of North AmericaIt was he most enduring contribution to marine biology,
92Ricketts BookA handbook to the rocky shores and tide pools of the Pacific Coast of the United States, first published in 1939 and now in its fifth edition. After 50 years this standard reference still reflects Ed Ricketts' considerable personality and enthusiasm for tidepooling and marine biology. Each intertidal zone is discussed in depth, augmented by black-and-white photographs and diagrams. Much revised, this edition includes the original forward by John Steinbeck and a tribute to Ed Ricketts.

96Friday Harbor Marine Lab - Friday Harbour, Washington Restricted to educational use, 500 acres campus, They do give periodic tours but some people drive through to get a feel for the lab.
100World War II - Effects on Marine Biology Sound Navigation Ranging - used in submarine warfare - based on underwater echoes Sonar
101Scuba - Self Contained Underwater Breathing Apparatus - engineered by Emile Gagne and Jacque Cousteau.It allows breathing underwater with compressed air.Dives are only limited to 165 feet. If you are going to go deeper than 165 feet, you must take an ROV.
102ROV - Remotely Operated Vehicle - controlled from surface AUV - Autonomous Underwater Vehicle - preprogrammed to their jobs independently of direct human controlAutomated Instrument Buoys - collect data while drifting with the current
103Autonomous Samplers - animals with date packages on them that collect live data, i.e., temperature, currents
104R/V FLIP - Floating Instrument Platform - provides a stable platform for Research at sea Satellites - capture the big picture where hurricanes are, how big they are, where they are going, where the eye is
106Method - observations - 5 senses: Taste, Smell, Hearing, SightTouchGoal - Decision of facts about the natural world and principlesto explore those facts.Scientific MethodScientific Method - observations senses: Taste, Smell,Hearing, SightTouchGoal - Decision of facts about the natural world and principlesto explore those facts.Tools - M Microscope - extend our senses.Macroscopic - observation - visible to the naked eyeMicroscopic - observation - invisible to the naked eyeObserve the part of the ocean (environment) and the organisms living there.
107Two Ways of Thinking· Induction - one uses separate observations to arrive togeneral principles.· Deduction - Reasoning from general principles to specificconclusions.Hypothes : IF “then” statement. Educated guess of what mighthappen.Experiment - stepwise process.Data - make tables/graphsAnalyze - comparisons etc. Compare to our control experiment under standard conditions.
