Above: Mosaic of aerial photographs of the St. Marks River (upper
center) and the estuarine system in Apalachee Bay (lower center), Florida.
Salt marsh (grayish areas on both sides of the river), seagrass (submerged
nearshore greenish dark regions), and oyster reef habitats (white linear
features near mouth of river) are clearly visible. Human development
(marina in lower left of image) are also visible.

Food web network in Jan and Feb grouped by cluster analysis class - smfin.kin
-
Food web network in Jan and Feb grouped by effective trophic levels - mjftnlv.kin
-
Food web network in Jan and Feb grouped by taxonomic names - sm921.kin
-
Use the Mage software (DOS executable file - simply run the file in Windows)
to open the *.kin files;
-
You can spin the network around by right clicking anywhere and dragging.
-
Positions of each node in the network were determined by a statistical
fit of the regular equivilance coefficients (trophic role similarity) using
multi-dimensional scaling (MDS)
-
The balls are colored using cluster analysis memberships (smfin.kin), effective
trophic levels (mjftnlv.kin), or taxonomic group names (sm921.kin).
The different colors of balls are indicated in legend on the right (check
each box one at a time; use "Complete" to see entire network). For
smfin.kin, the legend is:
-
Class 1 = producers
-
Class 2 = herbivores (suspension feeding and grazers)
-
Class 3 = herbivores (detritivores and grazers)
-
Class 4 = intermediate predators (mainly fishes and polychaetes)
-
Class 5 = top predators (birds and large fish)
-
Class 6 = Other compartments [benthic bacteria, meiofauna, benthic algae,
deposit-feeding crustaceans, POC (detritus) and DOC] - this class contains
nodes that did not group well with others based on regular equivilence
coefficients
-
You can determine the name of any compartment node (colored balls) by right
clicking on the node. The compartment name or number will appear in the
lower left corner.
-
The lines connecting balls are the carbon or energy flow arrows in this
network model (flow directions are not shown in this model). There
are some lines omitted for ease of display (like from every node to POC,
because everything dies and becomes detritus eventually).
-
You can zoom in to see nodes and connections better by clicking on "Zclip"
box and using the "Zoom" slide bar on the far right.

Seawater
Density Calculator - Sigma-T values can be calculated by visiting this
website at Dalhousie University
-
SIGMA-T table
- extraoplated from the table I gave you in class, but this one goes to
higher temperatures (the calculator in the website above will give more
precise answers, but these will be approximately correct).
