Historical Overview Of Tampa Bay Water Quality And Seagrass Issues And Trends, J.O. R. Johansson
Historical Overview Of Tampa Bay Water Quality And Seagrass Issues And Trends, J.O. R. Johansson
Reports
Historical (pre-1930s) seagrass meadows in Tampa Bay are believed to have covered 31,000 ha of the shallow bay bottom. Later, impacts to the bay from increasing population and industrial development of the Tampa Bay area have resulted in large seagrass losses. By 1982, approximately 8,800 ha of seagrass remained. Since 1982, Tampa Bay seagrass monitoring programs have recorded a reversal in the trend of seagrass loss, with the baywide seagrass cover increasing from 9,420 ha in 1988 to 10,890 ha in 1997. However, between 1997 and 1999 the trend again reversed with substantial losses recorded, specifically in the Old Tampa …

Recent Improvements Of Water Quality And Biological Indicators In Hillsborough Bay, A Highly Impacted Subdivision Of Tampa Bay, Florida, J.O. R. Johansson, R. R. Lewis Iii
Reports
Hillsborough Bay, the eastern uppermost section of the Tampa Bay system, is surrounded by a large metropolitan complex, supports extensive industrial activity, and serves as a major shipping port of fertilizer products. The Bay was determined to be highly eutrophic during the late 1960s. The City of Tampa's primary sewage treatment plant and runoff from fertilizer industry activities were considered as the major sources of excessive nutrient loading. Loadings form both these sources have been reduced during the last 10 years, which has probably been the leading cause of improved water quality parameters such as water clarity, dissolved oxygen, and …

The Bay Study Group intends to periodically monitor seagrass coverage, seagrass speciecs composition, and C. prolifera coverage within Hillsborough Bay and adjacent waters. Potential relationships between various environmental parameters and seagrass coverage will be investigated. Results should provide valuable information concerning natural seagrass renewal and rates of seagrass growth. Such information is much needed in order to make sound decisions concerning seagrass restoration and viable mitigation options.
