“…These findings are comparable to those of SANGER et al (2002) andWENNER et al (2004) who concluded that surges associated with storms that approached the east coast from the Atlantic generally cause short-term increases in salinity, while rainfall inputs result in longer-term salinity decreases. The observations in this study also support those of STEWARD et al (2006) were nearly threefold lower than 2003, although both years had extended periods of low salinity. In 2003, the period was restricted to August, the month when rainfall totals peaked.…”

“…In a Florida Bay study, MONTAGUE and LEY (1993) found that stations with large salinity fluctuations had relatively low biomass and unstable species composition. RID-LER, DENT, and ARRINGTON (2006) (STEWARD et al, 2006). Similarly, research on the response of fish communities to the 2004 storms showed an initial short-term impact but rapid recovery (PAPERNO et al, 2006;STEVENS, BLEWETT, and CASEY, 2006).…”

“…In the year following these storms, several studies examined the damage to Florida's coastal ecosystems (e.g., Lapointe et al 2006, Paperno et al 2006, Ridler et al 2006, Sallenger et al 2006, Steward et al 2006, Tomasko et al 2006, Wang and Horwitz 2007, Dix et al 2008, Carlson et al 2010). These studies found spatial variation in the amount of physical damage sustained by coastal environments and the resident flora and fauna (Greening et al 2006).…”

Nutrient enrichment intensifies hurricane impact in scrub mangrove ecosystems in the Indian River Lagoon, Florida, USA

Abstract. Mangroves are an ecological assemblage of trees and shrubs adapted to grow in intertidal environments along tropical, subtropical, and warm temperate coasts. Despite repeated demonstrations of their ecologic and economic value, multiple stressors including nutrient over-enrichment threaten these and other coastal wetlands globally. These ecosystems will be further stressed if tropical storm intensity and frequency increase in response to global climate changes. These stressors will likely interact, but the outcome of that interaction is uncertain. Here, we examined potential interaction between nutrient over-enrichment and the September 2004 hurricanes. Hurricanes Frances and Jeanne made landfall along Florida's Indian River Lagoon and caused extensive damage to a long-term fertilization experiment in a mangrove forest, which previously revealed that productivity was nitrogen (N) limited across the forest and, in particular, that N enrichment dramatically increased growth rates and aboveground biomass of stunted Avicennia germinans trees in the interior scrub zone. During the hurricanes, these trees experienced significant defoliation with three to four times greater reduction in leaf area index (LAI) than control trees. Over the long term, the þN scrub trees took four years to recover compared to two years for controls. In the adjacent fringe and transition zones, LAI was reduced by .70%, but with no differences based on zone or fertilization treatment. Despite continued delayed mortality for at least five years after the storms, LAI in the fringe and transition returned to pre-hurricane conditions in two years. Thus, nutrient over-enrichment of the coastal zone will increase the productivity of scrub mangroves, which dominate much of the mangrove landscape in Florida and the Caribbean; however, that benefit is offset by a decrease in their resistance and resilience to hurricane damage that has the potential to destabilize the system.

“…The IRL provides critical habitat for several dozen commercially and recreationally important fisheries valued at one billion dollars a year [28] and has one of the most diverse seagrass communities within the United States [29]. It also provides habitat to several endangered species such as Florida manatee (Trichechus manatus latirostris] [29].…”

Monitoring of the 2011 Super Algal Bloom in Indian River Lagoon, FL, USA, Using MERIS

2015

During the spring of 2011 an unprecedented "Super" algal bloom formed in the Indian River Lagoon (IRL), with Chlorophyll a (Chl a) concentrations over eight times the historical mean in some areas and lasted for seven months across the IRL. The European Space Agency's MEdium Resolution Imaging Spectrometer (MERIS) platform provided multispectral data at 665 and 708 nm, which was used to quantify the phytoplankton Chl a by fluorescence while minimizing the effects of other water column constituents. The three objectives were to: (1) calibrate and validate two Chl a algorithms using all available MERIS data of the IRL from 2002 to 2012; (2) determine the accuracy of the algorithms estimation of Chl a before, during, and after the 2011 super bloom; and (3) map the 2011 algal bloom using the Chl a algorithm that was proven to be effective in other similar estuaries. The chosen algorithm, Normalized Difference Chlorophyll Index (NDCI), was positively correlated with the in-situ measurements, with an R 2 value of 0.798. While there was a significant (62.9 ± 25%) underestimation of Chl a using MERIS NDCI, the underestimation appears to be consistent across the data and mostly in the estimations of lower concentrations, suggesting that a qualitative or ratio analysis is still valid. Analysis of the application of the NDCI processed MERIS data provided additional insights that the in-situ
