Oceanography and Ecology are synthetic sciences

Oceanography and Ecology in Early Federal Bureaus

Review | Key Players | Significant Idea | Summary | Start

Two fundamental ideas are not possible until the development of scientific investigations that focused on the sea and how species relate.

The biological redifinition after Charles Darwin of how all living things change over time to either ably adapt or to poorly adapt to extreme circumstances had to replace older observational errors:

    1. A rational approach to where different species lived had to replace the concept of a divinely ordained place for every living thing in an unfinished creation that humans could as dominant species transform to alter the world and creat a "second nature" to improve on what they called conditions of existence.

    2. Some functionally related set of concepts had to replace the idea that species did not change since they were created, because so many plants and animals were going extinct.

Opening paragraph:

"After The War between The States, the doleful predictions of George Perkins Marsh concerning fisheries and estuarine habitats churned in the mind of his confidant and supporter, Spencer Fullerton Baird. As a naturalist and assistant director of The Smithsonian Institution.

Baird knew that sport and commercial fisheries were dependent on anadromous fish. These fishes lived most of their existence in the sea but required the freshwater river sources to spawn The next generation of salmon, herring, or shad. Often the juveniles of these species lingered in The estuaries, where a rich supply of food, nourished the young."

Review of Chapter Five's main points:

Fishing and hunting interests before the war influenced Post Civil War Preservation impulses.

Oyster fisherman's plight pointed up the need for federal intervention.

Baird's Fish Commission (1871) drew heavily on the naturalists and the natural history tradition.

New Federal Bureaus like the Smithsonian Institution (1846) & Department of the Interior (1849).
Lack of Congressional support for government science.

John Quincy Adam's Internal Improvements drew opposition despite the obvious needs.

Coastal fortifications and mapping

Jacksonian creation of the US Coast Survey, 1832.

Alexander Dallas Bache (1842) transformed the Coast Survey.

Navy Depot of Charts and Instrument 1842, and Naval Observatory.

Lt. Matthew Fontaine Maury and the US Exploring Expedition.

Maury, 1851, new global map of Winds and Currents.

Physical Geography of the Sea, by Maury, based on Humboldt and Goethe's influences.

Military (Maury) & civilian (Bache) rivalry, notwithstanding yielded valuable natural history of the nations' and world's seashores.

Biological and geographical information about seashores, currents, tides and fisheries grew.

Specialists began to replace the naturalists (generalist) in government science.

National Academy of the Sciences, NAS, (1863) marked the ascendancy of specialists.

Specialists in federal sciences who studied fisheries, agriculture, geology amd biology changed the way professional investigators understood the natural world.

Habitat science in coastal studies, Manx naturalist, Edward Forbes described littoral zones with reference to their depth.

Niche was defined by naturalists as routine place of residence and occupation of means of extracting a living, securing a living in the economy of nature.

The actual name for a recessed space in a wall as applied to architecture was taken from the Italian word, nichio, for the interior of a bivalve sea shell.

Father and son team of Louis and Alexander Agassiz popularized the works of Dana, Forbes and Gosse to a wider audience.

Forbes described zones of depth and

Gosse described Devonshire coastal marine life of the rocky shore and sand beaches .

Louis Agassiz of Harvard was an important marine and fresh water scientist of invertebrates.

His influence was felt through his students, his Museum of Comparative Anatomy & his summer school to study seaside biology.

Louis Agassiz was a curious mix of modern (Ice Age) and antiquated (anti-Darwinian) ideas.

Louis Agassiz described the coral reefs along the Southeastern Florida coasts (1850s).

Alexander Agassiz, in 1865, published Seaside Studies in Natural History, described coast habitats of sandy beach, rocky shore, and mud flat.
Alex Agassiz described the organic realms of seaside creatures in zones, after Alexander Von Humboldt's Torrid, Temperate and Frigid zone classifications.

Agassiz oceanic zones were remarkably accurate.

Substrate (shore materials, rock, sand, mud) were described as restricting certain life forms.

A. Agassiz recognized the favorable conditions of tropical Florida reefs to rich and varied fauna.

Spencer Fullerton Baird was more of a naturalist later influenced Fish Commission & Biological Survey, hired C. Hart Merriam there at the Survey.
Line vs. trap fisherman argued over the causes for New England's coastal fishery decline 1870.

US Fish Commission created to resolve such disputes by looking into the science.

Fishery conservation was the first institution to promote science based protection policies at the federal level.

Dams were destroying river fisheries as well as coastal.

Lumber and mill interests opposed fishery conservation.

Fish hatcheries were promoted along with fishery science.

Brought national attention to European Science.

    1. depth and tides,
    2. zones,
    3. species life cycles,
    4. food chains, and predator and prey research,
    5. mathematical models of population change over time,
    6. conditions of salt and fresh water,
    7. fishery research.

Origins of the importance of and roles of the oysters in estuaries.

Karl Möbius' discussion of an Oyster Reef as a single entity or biocoenosis (biotically functioning assemblage) or biocenoses

"the entire . . . community would be transformed." by changes in external conditions.

Oysters are a keystone species in river mouths in that other creatures depend on these assemblages of organisms–called filter feeders, because they strain diatoms out of the water–in order to exist. Other creatures feed on the oysters, and still others like worms and barnacles grow on the oyster reef.

As indicator species oysters must have a certain water quality and hence quantity of fresh water to dilute with sea water in order to thrive.

As a sentinel species the oysters will not survive high salinity or in waters too fresh; and if too polluted the people eating oysters can get sick. When oysters die the community collapses that depend on them ecologically and commercially, so they guard the quantity and the quality, the timing and the distribution of water, nutrients, detritus and creatures dependent on these narrow conditions in river mouths.

More on keystone species.

Ernst Haeckel's contributions to nomenclature and evolution: Origin of the word oikologie, or ecology.

C. Hart Merriam's concept of Life Zones applied to San Francisco Mountains, in the Sonoran desert, of Arizona.

As you move up a mountain it is similar, with respect to vegetation, to moving towards the poles, from: tropical, to temperate, to frigid zones.

Each zone is characterized by distinctive types of plants, fungus and animals.

The zones can and do inter mesh but are characterized by distinct associations of dominant plant species and their dependent animals.

Organic approach to federal policy making is a thread and theme from 1871-1907.
River conservation was multipurpose in that it had many goals at once: flood prevention, wildlife protection, navigation restoration and reclamation as a form of conservation of land–at the expense of coastal, riparian, and inland wetlands needed by fish and birds.

"...remarkable rebuttal of laissez faire political economy."

Because if every individual pursues their own, self-interest, especially in tide lands and along river marshes and swamps–lakes or wetlands– the entire community of life, even the commercial dependence on timber, fisheries, and navigation can be so damaged as to require constant repair if not "restoration of disturbed harmonies."

George Perkins Marsh understood the river was a unit, Gifford Pinchot would come to see that, and Aldo Leopold would provide Rachel Carson with the needed coherence of conceptual thought to see how the seashore was a litmus test for the success or failure of conservation, preservation, and use in the protection of coastal regions on which the life of the sea depends.

"Somewhat ambivalently, tidal marshes had been recognized as essential habitats for fish and fowl while still being viewed as wastelands–after 1890, they were seen as a surrogate frontier of reclaimable farmland and homesteads to fulfill the popular promises of Progressive political and social ideology."
