According to reports, scientists from James Cook University in Australia recently announced that new research indicates that ships traveling through the Great Barrier Reef may interfere with the ability of whale to communicate.
Last year, scientists used large underwater microphones to record the sounds that could be heard within three months of a coral reef in Townsville, a coastal city in Australia. Prof. Colin Simpfendorfer, who was responsible for analyzing the research recordings, stated that the microphone recorded three major sounds, including background noise from weather changes, sounds from whales and other marine organisms, and the roar of ship engines. sound. He said: "The frequency of the (low-frequency) noise produced by the ship and the whale communicate with each other is almost the same."
However, Simpfer has also said that due to the preliminary stage of the research, it is not yet possible to determine how the engine sound will affect whales, but the increase in the number of vessels may raise concerns about related issues in the future. Because whales use low-frequency sounds to communicate with their peers, a significant increase in noise will likely affect whale's ability to communicate long distances.
Simpfer said that there is almost no research on how ship noise affects whales, and he hopes to find more to help scientists research the issue in depth.

How to Select the Best Grow Light for your Greenhouse?
The plant needs light to thrive cause the light is essental for photosynthesis.without it,plants can not make food.but light can also be too intense,too hot or last too long for growing healthy plants.plant growth accelerates with abundant light because more of the plant`s leaves have exposure,which means more photosynthesis.in the winter,days are not long enough,but many plants still need 12 hours or more of light per day.
Now,adding led grow lights to your greenhouse is an nice choice if you live in the north, and can not get enough daylight in winter.you might be take HID into consideration,cause it has high output and cover a wide area.but now,we providing you some dfferent.the newest type of grow lights use LED technology.
Provides Maximum Light Density and optimizing spectrum(410nm-740nm,white)
as we know that the plants need more light from the blue side of the spectrum during their seedling stage and when developing foliage and require light from the orange to red side of the spectrum while inblooming and fruiting phases. We adopting lastest intergrated COB technology, white , more red and blue PAR(410-740nm) per Watt than any other lighting fixture for the best color uniformity.
Dual Veg and Bloom for plant growth and bloom
the Led grow lights feature selectable VEG and BLOOM light spectrums to deliver maximum performance from seeding through the flower stage and finally harvest.
Increase yields and potency
using high quality lense that hyper-focus the lights on your canopy.the photons are beamed directly to the plants.this gives growers the ability to get greatest possible crop yield.
Reduce your costs with energy efficiency
energy-efficient cannabis grow lights cost between 40%-60% less to operate compared to HID lam year.
Led grow light also eliminate the needs for ballasts and reflectors while they minimize the cooling systems,accelerating your payback.you will see the electrical bills trimmed by approximately half,year after year.
Installs and operates simply
the input voltage is AC100V-240V,fit for the world standard,built-in power supply.do not need other equipment,just access to the Plug,the lamp will be work smoothly. The led grow lighting is small size,just few inches and easy to install.it is the good option for some greenhouse.
Long lifespan
using built-in quiet fans and the shutter in the wind,induced draftfrom all sides.runs with quiet. Useadvanced isolation power supply and soft start protection technology, to prevent the high voltage when turn on the light from damagingthe lamp body.
Our professional full spectrum LED grow lights are suitable for all the indoor plants and good for seeding, growth,flowering and fruiting stages of plants, increasing the harvest and Saving energy.
