1. Introduction: Write one paragraph that states the objectives or your study. (10 1713-)
ll. Methods: Write one paragraph that summarizes your collection of data using the SONDE 6600
and collection and filtration of samples for dissolved phosphate and silica.
Write a second paragraph that summarizes your laboratory analysis for dissolved phosphate and
silica. (15 P13.)
III. Results and Discussion.
You are asked below to prepare graphs and discuss the vertical and horizontal distributions of dissolved
phosphate and silica for September 16, 2015 (Listed west to east, stations 1, 3, 5, 6, 8.3, 8.2, 8.1
and 7), and water column parameters from both the August 26, 2015 and September 16, 2015
surveys of Crane Creek and the adjacent IRL (Stations 1, 3, 5, and 7).
Because of the large data set with 4 different parameters from vertical SONDE profiles at numerous
stations, you are asked to look at just 3 aspects of the overall data set. Your student colleagues
will have some overlapping and some different components of the data set to assess and present.
A. Vertical and Horizontal Distribution of Dissolved Phosphate and Silica
(Graphs 15 pts, Discussion 10 pts.)
a. Prepare 2 sets of graphs that show the distribution of (1) dissolved phosphate and (2)
dissolved silica in the horizontal perspective at each station for three water depths of
Surface, 1.0 m and 2.0 m (data are not available for all depths at all stations; you
decide whether to connect the lines when a data gap exists). The graph on the next
page shows you a start to one approach to the task using salinity (instead of phosphate
and silica) at 2 depths. You may plot one depth per graph or put multiple depths on
the same graph. Please use your own creativity and experience as needed to produce
a graph that works for you.
b. Describe the’ vertical and horizontal distribution of dissolved phosphate and silica
from upstream to the IRL in the context of a salt wedge estuary. Describe the main
trends at each depth and any anomalies that you find. (2 paragraphs)
F lgure 1. Salinity versus station number for water depths of 0.25, 0.5, 0.75, 1.0, 1.5 and
2.0 In for Crane Creek and adjacent Indian River Lagoon for August 11, 2011.
B. Plot the following: surface concentrations of (1) dissolved phosphate versus temperature
and (2) dissolved silica versus temperature of all eight Sept 16 stations.
(Graph 10 pts; Discussion, 2 paragraphs, 10 pts.)
Then, discuss (in 2 paragraphs) your interpretation of the phosphate and silica versus
temperature graphs. Do the graphs show any trends? If the trends seem ve com licated
try to describe some aspects of the observed trends.
C. Temperature Time Series (Graph 10 pts., Discussion, 10 pts.)
(a) Prepare a graph that shows the distribution of temperature in the horizontal perspective at
stations 1, 3, 5 and 7 for water depths of 0.25 m, 0.5 m, 1.0 m and 2.0 m for both August 26
and September 16 (data are not available for all depths at all stations; you decide whether
to connect the lines when a data gap exists). The graph on the next page shows you a start
to one approach to the task using salinity (instead of temperature) at 2 depths. You may plot
one depth per graph or put multiple depths on the same graph. Please use your own creativity
and experience as needed to produce a graph that works for you. You should be able to use
the graph that you prepared for Laboratory 1 to help with this exercise.
Corres: ondin Station Numbers
Set 16
Station 7 at two different IRL locations
(b) Describe differences in the vertical and horizontal distribution of temperature from
upstream to the IRL for the two different dates. Describe the main trends at each depth and
any anomalies that you find. (2 paragraphs)
IV. Conclusions
In one super-well thought-out paragraph, what are your conclusions from the data that yo_u
discussed above. (10 pts.)
