Stable isotope (13C) and O2 micro-optode alternatives for measuring photosythesis in seaweeds Article (PDF Available) in Marine Ecology Progress Series · January with Reads. Jul 22,  · Algal blooms or harmful algal blooms (HABs) are observed more and more frequently in inland and coastal waters because of the increased anthropogenic effects and enhanced monitoring capabilities in situ and from space.

These blooms usually manifest higher [chl-a] in comparison with typical water conditions in the area, and the fluorescence signal can be used as an additional proxy.

Algal products can be used for performance improvement and the reduction of pathogenic bacteria. Algae can be served in different forms – whole seaweed meal, powder, extract, homogenate or. Publisher Summary. This chapter provides an overview to the current knowledge on the oceanic distribution and pathways of nitric oxide (NO), nitrous oxide (N 2 O), dinitrogen (N 2), and ammonia (NH 3), which has increased considerably since the publication of “Gaseous nitrogen compounds in the sea.”These compounds play important roles in the chemistry and climate of the present-day Earth.

InPringsheim (Fig. e), at that time working in Halle an der Saale, Germany, published the first of a series of important papers on algal culture methods (of the numerous contributions which followed over a long period untilhis book Pure Cultures of Algae in and its German translation of were most highly influential).

with methods developed for the algal biofilms in this study. For now, productivity of the algal biofilms needs to be maximized in order to fully utilize its potential as a biofuel feedstock and nutrient removal option. Further research on algae-bacteria interactions using species native to the wastewater grown algal biofilms is recommended.!!Author: Maureen Kesaano.

The number of studies concerning Submarine Groundwater Discharge (SGD) grew quickly as we entered the twenty-first century. Many hydrological and oceanographic processes that drive and influence SGD were identified and characterized during this period. These processes included tidal effects on SGD, water and solute fluxes, biogeochemical transformations through the subterranean estuary, and Author: Makoto Taniguchi, Henrietta Dulai, Kimberly M.

Burnett, Isaac R. Santos, Isaac R. Santos, Ryo Sugimo. Methods for the aquaculture of ire F shrimp have been previously developed.

Some challenges presented by Fire shrimp are the long larval stage and their aggressive behavior as juveniles during grow-out. We describe the system and methods that produced juvenile Fire shrimp with a survival rate of 72% from day 2 through settlement (day ).

The mean number of benthic algal taxa per month ranged from to among streams. of ammonium and nitrate in the sediments of a tidal freshwater marsh were estimated from measured rates of isotope dilution of ammonium [15N] added to sediment and litter samples, reduction of nitrate [15N] to ammonium[15N] in fresh sediments, and net.

Modern GIS methods for calculating lake volume improve on more dated technologies (e.g., planimeters) and do not require potentially inaccurate assumptions (e.g., volume of a frustum of a cone), but most GIS methods do require detailed bathymetric data, which may be unavailable.

We used stable isotope analysis (SIA) of δ13C and δ15N. Sep 23,  · Although biogeochemistry is an integrative discipline, terrestrial and aquatic subdisciplines have developed somewhat independently of each other.

Physical and biological differences between aquatic and terrestrial ecosystems explain this history. In both aquatic and terrestrial biogeochemistry, key questions and concepts arise from a focus on nutrient limitation, ecosystem Cited by: page 1 shifting nutrient forms and ratios: implications for harmful algal blooms and nitrogen cycling in a subtropical estuary by joshua r.

Protocol for Developing Nutrient TMDLs Introduction and Purpose of This Protocol Objective: This Total Maximum Daily Load (TMDL) protocol was developed at the request of EPA regions, states, and tribes and is intended to provide users with an organizational framework for the TMDL development process for nutrients.

Methods for selective extraction and fractionation of algal lipids and algal products are disclosed. A method of selective removal of products from an algal biomass provides for single and multistep extraction processes which enable efficient separation of algal components.

Among these components are neutral lipids synthesized by algae, which are extracted by the methods disclosed herein for Cited by:. Unfortunately, this book can't be printed from the OpenBook. If you need to print pages from this book, we recommend downloading it as a PDF.
