Harmful algal blooms (HABs) have increased in abundance and severity around the world in recent decades. Among coastal HABs, benthic cyanobacteria blooms, particularly Lyngbya spp., are becoming more numerous and persistent in tropical and subtropical environments. These species have become increasingly problematic in the near-shore waters of Florida, and it has been suggested that this may be in part caused by nutrient enrichment resulting from highly developed coastal habitats.

Fisheries research funded by the NOAA Chesapeake Bay Office (NCBO) provides science and information to enable natural resource managers to make informed decisions. The NCBO Fisheries Science Symposium is a chance for fisheries scientists in the Bay area to present their research findings and create collaborations. This document is an EcoCheck/NCBO collaboration and summarizes some of the key topics presented at the 2009 symposium.

Rock Creek Park (ROCR) is a forest and wetland oasis in the heart of Washington, D.C. A National Park Service natural resource condition assessment (NPS NRCA) was conducted using two synthetic frameworks: 1) an ecological monitoring framework, and 2) a habitat monitoring framework. Data metrics and thresholds were determined and monitoring data applied.

This report card provides a transparent, timely, and geographically detailed assessment of 2008 Coastal Bays’ health. Prepared annually, the report card rates six reporting regions of the Coastal Bays, using six indicators combined into a single overarching index of health. Health is defined as progress towards established scientifically derived ecological thresholds or goals. The overall health of Coastal Bays was moderate in 2008, obtaining a grade of C+.

While engaged in professional oceanographic research and teaching, Marshall, like the postman who goes for a hike on Sundays, spent much of his free time cruising in his 30-foot auxiliary sloop. Underway he realized that, with the equipment readily available on vessels, whether large or small, interested observers could learn a great deal about their surroundings. This prompted him, in his retirement, to write Oceanography: An Observer's Guide.

The Florida Department of Environmental Protection (DEP) is developing a new transparency standard for marine waters that will protect the seagrass species found throughout the state. The current transparency standard does not sufficiently protect seagrasses, and the new standard will help DEP identify waters in which transparency is too low for healthy seagrass beds.

The central Kura River basin is a large river basin in the mountainous South Caucasus region of Eurasia. It contains important water resources for three countries—Georgia, Armenia, and Azerbaijan—and has a combined population of some 17 million people. There are many threats to these shared water resources, including nutrient inputs, heavy metal pollution, and sediment erosion.
