Battelle presented an interim report to the Grand Lake St. Marys Restoration Committee during a recent meeting at WSU Lake Campus after reviewing nearly 75 prospective vendor proposals. Each proposal included potential lake restoration technologies to address algal blooms that have occurred in Grand Lake St. Marys.
Submissions were analyzed by type of merit, their form and purpose including:
Controlling Phosphorus loading (internal and external)
Promising proposals from Ag Solutions Group
Biomanipulation
Algaecides
The screening process allowed a closer look at which vendors should be engaged in a more detailed evaluation. From this evaluation, Battelle recommended an ensemble of solutions that could be considered to be pursued locally both in the lake and in the surrounding watershed. Each of the recommended solutions follows one or more of the eight action items recommended in the Grand Lake St. Marys Restoration Strategic Plan.
The Battelle recommendation plan was made possible through partnership with the Governor’s office, The Western Ohio Educational Foundation, Wright State, all four agencies including Natural Resources, Agriculture, Health, and Environmental Protection. The report represents potential short-term and long-term strategies.
One of several of the recommendations, to best meet our short term goals: Lake-wide alum treatment for spring 2012, which is planned with the help of the State of Ohio.
As more plans are completed they will be made available to the public. One of these plans calls for help from residents along the many channels around the lake. Watch for further information on this exciting plan.
A copy of this report will be made available on the LIA website: www.lakeimprovement.com
The primary goal of the Grand Lake Restoration Commission is to restore the health of the lake to ensure that the lake is functional for tourism use this year and every year thereafter. To help address this need, community leaders and volunteers came together in December 2009 to form the Grand Lake St. Marys Restoration Commission – a pioneering initiative dedicated to fostering the regional cooperation and resources needed for the environmental renewal and sustainability to the lake. Our initial efforts primarily focused on identifying the proven scientific strategies and technological solutions able to solve our environmental crisis.
Together, these partner agencies have identified various watershed and in/near-lake alternative best management practices (BMPs) that could be used to help meet the qualitative and quantitative restoration goals for Grand Lake St. Marys and its surrounding communities. Success of these partnerships is driven by the unique strengths of the collaborators wishing to identify new technologies and target entrepreneurial funding to bring them to market.

"There is no better illustration in science of the practical value of ecology than is afforded by the diatoms. The economic importance they are now [1921] seen to have might have been understood fifty years earlier [i.e, 1871] and some use might have been made of their value during that period of time, if the inter-relation of these remarkable plants with other forms of aquatic life had been prominent in the minds of investigators. As it is, they remained for many years little more than the playthings of microscopists, prized and wondered over because of their astonishing beauty, collected at great expense by enthusiastic amateurs, and illustrated in costly books, which may be searched through in vain for any hint of their worth outside of that belonging to their symmetry of form and striking loveliness of design."

One may almost say no diatoms , no oysters. Some curious observations have been made in this respect. Mr. Bartholomew reports that the Menhaden (a surface feeding fish of the herring family) is quite a consumer of diatoms. He writes as follows: "You will probably be astonished to know that a 200 millimeter beaker of Menhaden intestines will frequently yield, after cleaning 25 millimeter of diatoms. Years ago, I thought I was a collector but my hat is off to the Menhaden."

Sardines above 100 mm. feed primarily on diatoms, though copepods are at times prevalent. Among the adult sardines of 200 mm. or longer the food is mainly diatoms, and occasionally dinoflagellates or schizopods occur in major numbers.

....
"It turns out that it's all about oil. The copepods have specialised fat stores that act like weight belts, letting the copepods maintain their depth easily and avoid attracting predators' attention with unnecessary movements. Building up enough fat reserves seems to be an essential step before diapause can begin - these reserves automatically trigger diapause once they reach a threshold level."
...
"Pond explains that the unsaturated fats that are crucial for buoyancy control are found mostly in plankton algae known as diatoms, so having these to feed on is crucial for copepods' ability to diapause successfully. He now plans to look at whether similar mechanisms help control the movements of other animal plankton, such as krill."

Biogeochemical significance of silicon in the world oceans
http://www.nio.org/index/option/com_newsdisplay/task/view/tid/4/sid/23/nid/33
| ||
| Diatoms are the major autotrophic communities in the euphotic zone in most regions of the world oceans. One of the most essential nutrients for frustule formation (cell wall or, theca) in the diatoms is silicate (SiO3). Higher the availability of SiO3 faster and better is the growth of diatoms. While emphasizing on the pivotal role of Si in the biology of diatoms and radiolarians in the oceanic realms, Dr Ittekkot, in his seminar at NIO, cautioned that anthropogenic activities, in particular construction of dams on major rivers in the world, are causing reduced Si discharges into the oceans and affecting the growth and abundance of diatoms over there. Based on the available literature on diatom composition, abundance and pre- and post-obstructions of the reverine discharges he indicated that the diatoms are adversely affected and giving alarming signals of depleting phytoplankton assemblages post-obstruction. Evidences point to catastrophic effects at least in the ocean-margins on diatoms, the major, innocuous autotrophs in the oceans. With Si depletion but nitrate and phosphate in abundance, the dinoflagellates - many species of which are toxic to many marine and terrestrial life forms - bloom and bring in unwanted changes in the marine ecosystem including mass mortalities of aquatic fauna and reduced fish harvests. He also highlighted the role of Si in regulating C fluxes [higher C fluxes when Si is adequately available for phytoplankton] and suggested that a great deal of new science needs to be done to address the consequences of reduced Si reaching the oceans due to dam constructions world over. Dr Ittekkot also brought out that 2 micromoles of SiO3 in the euphotic zone is adequate for the normal growth and activities of diatoms. While the deep-sea SiO3 concentrations are much higher, the time taken to reach up in the surface layers is very long and, often may not make it to the surface layers owing to physical barriers such as upper layer stratification. He summed up the seminar by appealing scientific community to address the Si issue from both the proposed river basin connectivity and the long term consequences of ocean productivity and biogeochemistry in an altered Si cycling scenario. Dr Venu Ittekkot works at ZMT, Bremen, Germany. (Reported by: N. Ramaiah) |

MARINE PLANKTON DIATOMS OF THE WEST COAST OF NORTH AMERICA

MARINE PLANKTON DIATOMS OF THE WEST COAST OF NORTH AMERICA
BY EASTER E. CUPP
Volume 5, No.1, pp. 1 - 238,
Submitted by editors December 26, 1940
Issued March 13, 1943
Pg 33
"IMPORTANCE OF DIATOMS AS A SOURCE OF FOOD IN THE SEA
Diatoms have for many years been recognized as an extremely important source of food for plankton animals. Haeckel (1890), Johnstone (1908), Lohmann (1911), Gran (1912, 1930, 1931), Lebour (1921, 1922, 1923), Herdman (1923), Bigelow (1926), and Allen (1934b) have published valuable discussions of the problems involved in the abundance of life in the sea. Johnstone (1908) stated: “The Diatomaceae are above all the most important organisms in the sea regarded from the point of view of their significance as the producers of organic substance. The diatoms are the ‘pastures of the sea’ and correspond to the ‘grass of the fields’ of the land.” Gran (1930) wrote: “These enormous
quantities of diatoms, without doubt, are the most important food for the pelagic copepods and indirectly for the fish larvae which develop after the great spring spawning period.” Phifer (1933) likewise wrote: “Marine plants are the principal source upon which the fauna of the oceans depends for the energy necessary for existence. . . . Undoubtedly the shore algae produce organic material forming nutritive substances for bacteria which in turn are probably consumed by small protozoa. However, the phytoplankton are directly consumed and produce organic food in much larger quantities since the areal extent of their distribution is many times greater than that of the shore forms. Of the groups in the phytoplankton, such as diatoms, dinoflagellates, algal spores, coccolithophores, the first mentioned play the major role in temperate seas.” "
Diatoms were thoroughly studied from 19th Century but unfortunately the knowledge is not being used today to solve problems of water pollution and climate change.
