This book was released on 2006 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: A monitoring program was initiated in May 1987 to study phytoplankton in the Western Isles region of the Bay of Fundy, southwest New Brunswick. This report provides another 2 years of data to add to the results from 1987-98 published previously. Samples were collected for phytoplankton distribution and abundance as well as plant nutrients (ammonia, nitrate, phosphate and silicate) at five locations - Brandy Cove, Lime Kiln Bay, Deadmans Harbour, the Wolves Islands and mid-Passamaquoddy Bay. Additional parameters measured included secchi depth, and depth profiles for fluorescence, temperature and salinity. Samples were collected at the surface from all locations and additional discrete depths of 10 m, 25 m and 50 m at the Wolves Islands, and 5 m and 15 m depths were initiated in Lime Kiln as of June 2000. Dominant species (> 103 cells-L−1) during the 2-yr period were Chaetoceros socialis, Chaetoceros spp., Dactyliosolen fragilissimsu, Ditylum brightwellii, Eucampia zodiacus, Guinardia delicatula, Leptocylindrus danicus, Pseudo-nitzschia delicatissima group, Skeletonema costatum and Mesodinium rubrum. M rubrum and the P. delicatissima group have been observed at concentrations > 10,000 cells·L1 during all of the past 14 yr. Alexandrium fundyense (the organism responsible for producing paralytic shellfish toxins) concentrations exceeded 104 cells·L1 in all but 2 yr during the 1988-96 period, cell densities were 8.2 and 6.7 x 103 cells·L1 in 1997 and 1998, respectively, and the highest concentrations observed during 1999 were 3.2 x 103 cells·L1 in late July, while the highest densities recorded for 2000 were 2.5 x 103 cells·L1. During the 2 yr, the lowest temperature (1.0°C) was measured at Brandy Cove while the highest temperature was recorded at the mid-Passamaquoddy site (17.0°C), both occurring in 1999. Lowest salinities (21.19 psu) were measured at Brandy Cove. Nitrate values ranged from 0.09-12.10 μM; ammonia from 0.04-8.10 μM: nitrite from 0.05-0.68 μM; phosphate levels ranged frmn 0.29-1.26 μM and silicate from 0.30-19.7 μM

This book was released on 2007 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project investigated the feasibility and cost-effectiveness of several potential early warning approaches for harmful algal blooms at salmon farms in southwestern New Brunswick (SWNB). The components of this 3-yr project included: training farm personnel on the sampling, identification, and counting of harmful algal species; implementation of high frequency phytoplankton monitoring by farm staff at selected salmon farms; retrospective statistical analyses of existing monitoring data; laboratory experiments to determine threshold concentrations of selected harmful algae which can cause problems for farmed salmon; use of a water to predict the movements of blooms which may affect salmon farms; evaluation of the effectiveness of a light sensor array for bloom detection; and evaluation of the usefulness of satellite imagery for bloom detection. Training sessions for farm workers were held in July 2004 and May-June 2005. Training was provided on sampling techniques, the use of microscopes, and the identification and counting of harmful phytoplankton species. Phytoplankton monitoring was conducted by trained staff at four farms near Grand Manan Island in 2004 and at two farms near Grand Manan Island. And one farm in the Passamaquoddy Bay and one farm on the SWNB mainland coast in 2005. The goal was to have farm workers collect and analyze samples approximately daily from late spring to early fall. On average, samples were collected in about 60% of days in 2004 (July-September) and 75% in the 2005 (late May-September), while the numbers of samples analyzed represented

This book was released on 2007 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of the ciliate Mesodinium rubrum has been monitored at five locations in the Bay of Fundy, eastern Canada, at weekly to monthly intervals since 1987. M. rubrum was present at all stations an average of 94% of the sampling dates from 1987 to 2004. The date for the first appearance of M. rubrum in a given year was inter-annually variable and ranged from January to April. Maximum concentrations occurred anywhere between May and October and tended to be earliest at Lime Kiln Bay and the Wolves and latest in the more inshore Passamaquoddy Bay stations and Deadmans Harbour. Brandy Cove, the most inshore station in Passamaquoddy Bay, had the highest concentrations, suggesting that this region was more conducive to the higher cell densities and blooms of M. rubrum. The annual maximum concentration varied among stations and between years by up to 5.7 orders of magnitude. The median maximum value (cells·L−1) was 13740 (Station 3), 12600 (Station 15), 16400 (Station 16), 19460 (Station 17) and 70296 (Station 25). The annual duration of the presence of M. rubrum ranged throughout the year and had a mean of 224 d, whereas the duration of the presence containing the annual maximum concentration varied from 7-365 d. The characteristics of the annual M. rubrum blooms vary between years and stations with the number of blooms or high abundance periods varying from one to two per year

Available in PDF, EPUB and Kindle. Book excerpt: This long-awaited book about non-pollen palynomorphs (NPPs) aims to cover gaps in our knowledge of these abundant but understudied palynological remains. NPPs, such as fungal spores, testate amoebae, dinoflagellate cysts, acritarchs and animal remains, are routinely recovered from palynological preparations of marine or terrestrial material, from Proterozoic to recent geological times. This book gives the reader a comprehensive overview of the different types of NPPs, with examples from diverse time periods and environments. It provides guidance on sample preparation to maximize the recovery of these NPPs, detailed information on their diversity and ecological affinity, clarification on the nomenclature and demonstrates their value as environmental indicators. This volume will become the reference guide for any student, academic or practitioner interested in everything else in their palynological preparations.
