Summary
 The overlap of hurricanes and nesting seasons in the
southeastern US is a threat to the survival of sea turtle
nests.
 Students will explore real time data to understand the
relationship between storms and nesting success.
 They will be analyzing datasets within the SECOORA
website and drawing conclusions that will enable them
to predict future hurricane damage.
Key Concepts
 Natural events such as hurricanes impact sea turtle
nesting.
 Available real-time data is useful in predicting an
analyzing threats to sea turtle nesting.
 Archival data from past hurricanes can be useful in
modeling potential impacts on turtle nesting and in
mitigating the severity of future impacts.
Objectives
 Students will gather real time data from the
SECOORA website that focuses on physical
and chemical parameters.
 Students will record real time data and
retrieve archival data.
 Students will demonstrate the relationship of
real time data to natural weather occurrences.
 Students will predict damage from
future storms.
 Students will present and communicate
the results of their research by
comparing and analyzing data from five
different southeastern regions of the US.
Materials
 Computer
 Access to internet
 Paper/pencil
 Lab journal
 Ruler
Procedure
 Students will read the background papers and answer
questions on Baby Turtles and on Hurricanes.
 Students will break up into five groups each of which
is assigned a different southeast region of the US.
 Their assignments will be accessed online as files.
 The regions considered are North Carolina, South
Carolina, Georgia, northern Florida and southern
Florida.
 Each group will receive an article specific to their
region which they will summarize.
 They will acquire real time and archived data for
their area on wind speed, wind direction, air
pressure, humidity and water level.
 They will compare real time data with archived
data and answer related questions.
Data Analysis
 Go to www.SECOORA.org
 Click on Data and Maps
 Magnify the map and click on the platform close to
New Smyrna Beach.
 Complete Data table 1 with your real time data for
wind direction, wind speed, air pressure, humidity,
and water level. Include current time and date.
 Click on http://www.fldep-stevens.com/readings8721147.php
 This will allow you to find archive data. Insert August
25, 2011 to August 29, 2011.
 Compare your real time data to your archive data.
 Choose a date where you have the most significant
changes in either of the 5 variables you were
provided with. Complete Data table 2 with your
archive data. Include date and time of your
archive data.
 Be sure to include the date and time for your
archive data.
 (Have students convert water level from feet to
meters)
 Coordinates for New Smyrna Beach, Florida: 28-
58-43.9520N / 080-55-30.1950W

Assessment
 Students will collect and analyze data, comparing real
time data with archived data.
 Students will communicate their findings by
presenting their data to the class and sharing their
analyses of this data and their conclusions.
 Students will satisfy the requirements of the
assessment rubric.
 Students can create a board game on
hatchling survival.
 Students can create informational
posters on hurricane survival.
 Students can create educational
brochures on various species of
turtles.
 Students will develop strategies to
mitigate damage in future storms.
Using available data during a virtual field trip and
archival data relating to Hurricane Irene as a
benchmark, student research should focus on:
(1) climate change effects on key habitats upon which
turtles depend;
(2) factors that influence nest site selection;
(3) the consequences of skewed primary sex ratios; and
(4) the effect of climate change on turtles at sea, for
example range shifts and dietary breadth.

Questions to consider:
Which species are involved?
Where are nesting beaches?
What are the food sources?
What are the migration patterns?
What are the long-term threats? (Climate, Sea Level
Changes, Food webs)
What are the short-term threats? (Storms, human
activities/beach use, development, weather, pollution
events)

Recent human activities may serve as a model of long-term effects.
Ultimately, if turtles cannot adapt to the effects of climate change through
combination of physiological and behavioral mechanisms, they could face
local to
widespread extirpation without zealous management.
Turtles migrate and forage over huge spatial scales, which may also confer
greater resilience and adaptive capacity to the negative effects of climate
change.
Nesting, migration and foraging behavior should be integrated across
populations with increasingly reliable empirical and modelled climate
information to work towards assessments of adaptive capacity and
resilience of marine turtles to climate change. (Williams et al. 2008) This
could be facilitated by studying short-term impacts from human activities.
