Operation: Recover the American Lobster Population of the Long Island SoundMonika Brzostowska, Anastasia Deda, Elissa Olivera, Jiemin Yang at Queens College
Plan of Attack
1) Aeration
: Add dissolved oxygen to LISConstruct 10 artificial waterfalls in the Western part of the LIS by 2032 similar in design to that underneath the Brooklyn Bridge (Figure 2.)Monitor waterfall efficiency for 5 years to determine whether beneficial to install more2) Mixing:Mix dissolved oxygen into LISInstall jets underneath beach docks and on Sound floor to increase mixing of water in benthic zone (where the lobsters are) by 2042 3) Reduce Atmospheric CO2 In NYC: Sustain levels of atmospheric CO2 at 450ppm so there is only a 50% chance that temperatures will rise more than 2°C by 2100 (Houghton)4) Public Awareness: Educate NYC’s public and young generation about the negative effects of climate change on the Long Island Sound lobster population Increased knowledge about issue = More willing to donate = higher chance strategies will succeed

American
Lobster (Homarus americanus) population declined by 90% in Western LIS and 60-80% in Central LIS in 1990s (Pearce and Balcom)Due to 1 degree Celsius (1.8 degree F) increase in temperature between 1979-2002Since then LIS lobster population has not increased by more than 5%We aim to recover LIS lobster population by 85% of current population by 2102Why Are Lobsters Needed: Food/Income SourcePreserve Biodiversity in LISImportant for flow of energyWhy Should You Care?2011: Cases of people dying after eating LIS lobsters70% of Western Long Island Sound lobsterman lost 100% of fishing income (Balcom and Howell)
Aeration:Estimate the cost of the waterfalls - 1 monthFind sponsors, Create a website that has a donation sectionFind investors to invest in our cause, apply for grants – 5 yearsGet a permit from NY state government to build the bridge - 5 monthsClose off the area for construction and get base of waterfall in – 5 monthsConstruct waterfall with 135 feet height and 90 feet width – 1 yearHave the opening ceremony for the waterfall (get the public more aware and involved during this ceremony) – 1 DayRun waterfalls from 7am-9pm each day
Reducing Atmospheric CO2:Get rid of PlaNYC proposed by Mayor Bloomberg by 2013Issue rationing for how much carbon emissions each building can produce by 2020Build devices that capture carbon dioxide produced 2020Increase the efficiency of how electricity is made by 2030Build a nuclear power plant to provide for 80% of NYC’s electricity by 2030
Mixing:Have meeting to obtain government fundingSet up the first center with a large jet in New Rochelle and add ten smaller jets that are attached to docks and on Sound floor in Hudson Beach (New Rochelle) by the year 2022.Set up the second center with a large jet in Glen Cove and add ten smaller jets in Prybil Beach (Glen Cove) by the year 2032.Set up the third and final center with a large jet in Wards Island and add the final ten smaller jets in Hell Gate (Wards Island) by the year 2042.Install mesh protection around jets
Public Awareness: Via WebsiteCreate an “Operation: Save the Lobsters of the LIS” websiteUpload research about issue (every 6 months)Create Donation pageVia Social Media Build a social media marketing team by 2014. Build a Facebook page where we update about lobster study in Long Island SoundUse Social Media to promote website Use Twitter to expand our awareness-raising campaign Schedule and promote family and fundraising events regarding our cause Promote contests: donate $5 and might win free snorkling session in LIS

Fig.3. This
map shows the dissolved oxygen levels in the LIS. The lowest and most severe levels are concentrated in the Western LIS and gradually become less severe as you move eastward. This map shows the locations in which we will first start implementing our aeration/mixing strategies. The red area on map is the area that will be used to measure the effectiveness of waterfalls. It shows how severe the lack of oxygen is in the LIS.

Main Causes of Lobster Decline
Fig. 1. This
figure shows
the
main factors that work to decrease the lobster population in the LIS. It is organized in a cause and effect flow, designating which environmental conditions lead to the death of lobsters. From this chart we focused on trying to assess increasing temperatures and decreasing dissolved oxygen. Increasing temperature is the primary cause of the lobster death. Although assessing nonpoint source pollution as opposed to decreased dissolved oxygen seems the most logical, it is not the most practical as this type of pollution does not have an identifiable origin making it very difficult to asses.
Fig
. 2. This
figure shows three approaches we focused on when creating strategies that most effectively assess our issue of recovering the lobster population. These approaches pinpoint the two main components of the cause and effect flow chart (Fig. 1) and incorporate the reality of solving this problem in the public world. All four of our strategies were derived from these three approaches.
Fig. 4. This image shows
a previous model of our aeration strategy. The waterfall increases dissolved oxygen in LIS through turbulence. Increasing oxygen means more oxygen will sink to the benthic levels providing more oxygen to the bottom dwelling lobsters
. This added oxygen will be mixed by installed jets on the LIS floor.

Falling Oxygen”
Pros:
Similar
projects have already been
carried
out in different locations.
Waterfall
of similar design and cost on the Brooklyn Bridge funded as
artistic
structure without government assistance.
High
chance that we will receive funding based on a previous
example
Cons
:
Localized effects: Damage area and environment where it’s built
Expensive: Estimated cost per waterfall is $15 million (we are building ten)
Not proven that it will generate enough oxygen to recover lobster population by 85%
Aeration: Why We chose it
?
To
add dissolved oxygen into LIS
Pros: Effective, low cost waste treatment jet models to base our design Doesn’t take long to buildCons:Effects land directly around jet sitesMay create too much turbulence for organisms
Mixing: Why we chose it?Most effective way distribute dissolved oxygen to benthic levels in LIS
Capping CO2 in NYC: Why We Chose it? In order to make sure other strategies will continue to be effective
Pros: Prevents further increase of water temperatureNot solely aimed at LISTargets primary cause of issueCons:Very unlikely strategy will workNYC unlikely to sustain levels of 450 ppm in given time periodCO2 has very long life spanNuclear power plant will cause increase runoff into LIS
Education: Why We Chose it? Without it we wouldn’t receive the necessary funding and the damage would continue to get worse
Pros: Educating public decreases amount of damage done to environmentVery low costReceive necessary funding from donations Cons: Public won’t care about issue even after educatedGreat chunk of donations come from public awareness
