The Dangers of Algal Bloom

Never take for granted the small signs of algae in your water system: algae multiply quickly that they can almost swathe the entire pond or lake and, worse, destroy the pond and its inhabitants.

These tiny plant-like organisms grow drastically in any water features, whether on fresh water or marine environment. The rapid increase of algae is popularly known as algae bloom. The existence of phytoplankton species can aggravate the growth of algae. Algae bloom can manifest anytime, particularly during summer or spring, and thrive in any places where water is copious such as wetlands and waterways.

Algae are part of the natural aquatic ecosystem. They provide food and protection to fish and other marine organisms. They help the aquatic ecosystem from getting enough nutrients and filtering heavy metals. There are approximately 3,000 species of fresh water algae found in Australia alone, but the number of undiscovered species is continuously rising.

Most types of algae produce blooms that can be either beneficial or toxic. Blooms produced from diatoms promote the health of the aquatic ecosystem. However, most algae blooms are considered “detrimental” to the life of fish and water. Harmful algal bloom or HAB is the term used by scientists when referring to toxic algae.

Algal bloom is a natural phenomenon that can be a culprit for the destruction of commercial fisheries and natural water systems. There are 300 reported species of micro algae that produce enormous mass of algal blooms. Certain species can turn clear water into red, brown, yellow, or green, commonly known as red tides. Red tide happens when there is unbalanced number of microscopic algae Karenia brevis or formerly known as Gymnodinium breve. Experts believe that red tide is triggered by high temperatures and insufficient wind and waterfall.

Harmful algae can be very harmful for they emit toxin that affect marine organisms and the water itself. Untreated and uncontrolled algal bloom can bring massive problems to commercial fisheries, resulting to economic loss in coastal communities. HABS can paralyze aquaculture operations and affect the livelihood of fish farmers,

Otherwise, harmful algae bring much problems to marine life and humans. Some toxic species are responsible for various diseases such as loss of memory, stomach cramping, sickness, paralysis, and worse, fatality. Once consumed or direct contact occurred, humans and animals may get serious diseases and may also lead to death

Scientists have not traced yet the exact causes and solutions for harmful algae bloom. The threats of algae bloom to commercial fisheries and public water systems have spurred panic among pond and fishery owners. The notorious algae bloom has been a global problem. There have been documented cases of HAB across the world. In recent years, HABS have been found in areas that they had not thrived before; while most HABS are causing turmoil to large, dense areas. Whilst, there are rare cases wherein algae bloom tend to behave, but they suddenly became untamed and caused problems.

When small signs of algae infestation arise, you must be equipped with tools and water treatment products to prevent algae from coming.

Temperature Monitoring And Alarm System For Biorepositories

Accsense System Enables Compliance with Title 21-CFR part 11

CHESTERLAND OH-March 19, 2012

Medical storage repositories and biobanks constantly work to comply with increasingly demanding FDA regulations, especially Title 21-CFR part 11, in the storage of their temperature-sensitive life science products. Unfortunately, medical freezers often fluctuate in the mandated -40??C to -200??C range due to uneven cooling and prolonged door opening among other causes. CAS DataLoggers now offers biorepositories an ideal solution with the Accsense A2-05 Wired Ethernet Temperature Data Logger, an automated temperature monitoring and alarming system specifically designed to protect customers’ valuable life science materials. These LAN-wired temperature monitors are equipped with connections for external RTD and thermocouple sensors, using a standard Ethernet connection to the Internet to automatically send all data to secure servers. In addition to cloud-based data storage and reporting functionalities, the Accsense system also offers email, pager, and phone alert capabilities to form a complete and cost-effective monitoring system. Now customers can view and remotely access data in real-time, transmitting recorded temperature data online for easy storage and analysis, entirely eliminating all the worries over regulatory concerns raised by manual temperature checking.

These reliable data logging pods connect to medical refrigerators, freezers, and cryogenic tanks to provide high accuracy monitoring for every storage unit. Each A2-05 datalogger supports Power over Ethernet and has inputs for external sensors including 2 RTDs and a thermocouple, with available temperature RTD probe accessories measuring a -100??C to +100??C temperature range for ultra-low containers. Customers can also choose a Type T thermocouple cryogenic probe measuring from -200??C to +-100??C to monitor liquid nitrogen containers and tanks. An ambient temperature probe measuring 0??C-100??C is also available, and for additional flexibility, A2-05 data loggers can be mixed and matched with Accsense wireless monitors if other parameters need to be monitored. By connecting an RTD input to a switch monitoring freezer door opening and closing, sudden temperature fluctuations can be quickly identified and configurable alarms can be set to prevent loss of high-value goods.

The Accsense system’s advanced capabilities offers users online graphing, reporting, and configuration features enabling compliance with Title 21-CFR part 11 and legal liabilities by closely monitoring and recording sensitive goods in storage. All the system requires is an RJ45 Ethernet connection with open internet access to begin recording, without any need for troublesome installation. Accsense dataloggers automatically send all recorded data to Rackspace, the manufacturer’s completely secure cloud server, where it is immediately stored and available using a backed-up online Accsense Account. Customers’ accounts give instant access to charts showing all measurement history with ranges as narrow as 5 minutes or as wide as 90 days, and also offer a customizable interface with a dashboard showing the most recent measurements from all sensor pods. Measurement data can also be downloaded for offline analysis, and multiple monitors can be viewed in a single account.

Accsense installations are simplicity itself, offering turn-key operation and entirely eliminating the need for IT professionals or costly training programs. Since all the data instantly goes out to the Web, Accsense is the only system on the market that has virtually NO impact on the existing infrastructure, including server structure, IT overhead, and only a minimal impact on bandwidth. Staff times are significantly decreased by gaining real-time access to the current temperature data. Also, unlike many integrated systems on the market forming control issues, Accsense systems offer users peace of mind and secure operation.

Each wired temperature monitor includes a power adapter and Ethernet cables for a lower cost and easier maintenance compared to traditional wiring, increasing life science safety measures. In the event of a loss of the network connection, they will store up to 256 data points or until the connection is restored.
