Crunching the Numbers: Light Intensity on a Hawaiian Coral Reef

By Dana Riddle/ Part 12

I had the pleasure of living on the Big Island of Hawaii for 18 years and took every opportunity to study the coral reefs there.

One of the projects involved taking light measurements at various depths. This might sound like an easy task, but it wasn’t.

The ocean had to be relatively calm as these were shore dives. Excessive wave action would make entering the water a dangerous proposition and would have also made the water turbid.

I had to be in the water suited in SCUBA gear at noon on a clear day near the summer solstice. I used an Apogee Instruments’ quantum meter in a custom-built underwater housing and used the depths reported by my dive computer.

After repeated attempts, I finally had some useful data.

The ocean water off the western coast of the Big Island is some of the clearest (technically ‘least turbid’) in the world. There are no rivers or streams entering the ocean there and the water is classified by the Swedish scientist N. G. Jerlov as Type I Oceanic water hence the light intensity is close to the maximum experienced by corals. See Figure One.

While this is interesting, we can further refine data. The July photoperiod in Hawaii is about 13 hours.

If we use the maximum light intensity and start and end with zero light intensity, we can estimate Photosynthetic Photon Flux Density (PPFD) throughout the day. See Figure Two.

The next step is calculating the Daily Light integral (DLI). While a PAR meter reports the number of photons falling upon a surface in one second, a DLI calculates the total number of photons falling upon that surface during the entire photoperiod.

This was done by estimating the light intensity in 15-minute increments and multiplying the number of photos per second. (Example: 100 µmol˖m²˖sec * 60 seconds per minute * 15 minutes = DLI for that 15-minute photoperiod.)

This procedure was repeated for every 15-minute increment and summed. We arrive at a large number; hence it is divided by 1,000,000 to arrive at Mol photons per photoperiod and that number is 21.

Can we replicate this amount of light in an aquarium? We probably don’t want to since a PPFD value is above the Saturation Point of many zooxanthellae species/clades.

Using algebra, we work the DLI value backwards. I’ll use a photoperiod of 12 hours.

21 DLI * 1,000,000 = 21,000,000 divided by number of seconds in the photoperiod (126060 = 43,200) = 486 µmol˖m²˖sec.

It is entirely possible to provide the same amount of light to an aquarium coral as it would receive at 40 feet on a natural reef.But a cloudless day is a rarity in Hawaii.

Next time we’ll look at light intensity on a cloudy day.

The Xanthophyll Cycle – A Pressure Relief Valve for Photosynthesis

By Dana Riddle – Part 11

Dana Riddle has been writing a series of articles regarding photosynthesis and the effects of variously colored Light-emitting Diodes.

If you have missed, please find here the link to PART 10 . You will find all the previous articles there if you wish to recapitulate or start following them.

A natural process exists that offers some protection to zooxanthellae when exposed to too much light – this is called the Xanthophyll Cycle.

This short article will explain what this is and how this works.

Xanthophylls (Xantho is Greek for ‘yellow’ and phyllon for ‘leaf’) are carotenoids.

These are seen during the Fall when leaves change color, but they are found in aquatic environments as well.

In Symbiodinium (zooxanthellae) there are two xanthophylls – Diadinoxanthin (DD) and Diatoxanthin (DT).

During periods of high light intensity, diadinoxanthin is converted to diatoxanthin and is called Dynamic Photoinhibition.

The conversion of DD to DT shunts energy away from the photosynthetic apparatus and acts as a ‘pressure relief valve’ for photosynthesis.

Scientists call this ‘non-photochemical quenching’ or NPQ. This process takes place in just a few minutes upon exposure to strong light.

At night, or periods of low light intensity, the process is reversed – diatoxanthin reverts to diadinoxanthin.

Absorption-Spectra-of-Xanthophylls-Found-in-Zooxanthellae — **Figure 1. Xanthophylls found in zooxanthellae strongly absorb violet and blue light. Absorbed energy converts diadinoxanthin to diatoxanthin thus shunting energy away from the photosynthetic process.**

Understanding Dynamic Photoinhibition is important.

Unfortunately, it is not within the reef aquarium hobby and has led to the misconception that Symbiodinium photosynthesis begins to slow after a few hours’ time regardless of light intensity.

This has led to lighting regimes called ‘zig-zag’ and ‘saw tooth’ patterns. This is not to say these patterns can’t lead to success.

Based on observations I made during my 18 years in Hawaii, the DD/DT cycle begins to regulate photosynthesis in shallow water corals in early morning (generally when light intensity reaches 300 to 400 µmol·m²˖sec.)

The conversion of DD to DT offers limited protection to high light intensity.

If light intensity exceeds the abilities of xanthophylls to protect the photosynthetic apparatus, then another sort of photoinhibition occurs and is called Chronic Photoinhibition.

Long-term Chronic Photoinhibition can lead to damage of both zooxanthellae and the coral host.

Energy that could be used for growth or reproduction is then directed to tissue repair.

Next time, we’ll look at light intensities at various depths at noon in some of the clearest (or more correctly, the least turbid) ocean water in the world – the Kona coast of the Big Island of Hawaii.

In extreme cases, the coral will expel zooxanthellae in a last-ditch effort for survival.

Review Orphek Filter Macro Corals Lens For Smartphone

The Best Smartphone Coral Lens Kit for 2020

Review by Ryan Cunningham

So I have had more time to spend with the new orphek aquarium lens and I have to say the quality of my pictures have increased notably in my opinion.

Not trying to toot my own horn or anything because let me tell you, ALL the credit to my new photography skillz must go to this lens!

All the lenses are made of high quality glass, no plastic lens here! This leads to clearer pictures and a longer lasting lens because less prone to scratching!

Also there are multiple different lenses that you can mix and match with and the macro lens is very accommodating, you don’t have to be SUPER close to the corals to use it like most other macro lenses I have used.

Check out these pictures and videos I took with this lens and let me know what you think! Thank you for the blessing of good pictures Orphek!!

Orphek OR2 reef bar LED as an alternative to T5

LED vs T5

By Tony / www.coralcompass.co.uk

T5 technology has been a trusted source of lighting for marine aquarists for many years. Relatively inexpensive to buy and replace T5 florescent tubes have provided a uniform tank wide light source, which has enabled reefers to grow corals successfully.

LED marine lighting technology has evolved and is becoming increasingly popular due to its efficiency and controllability, however it has limitations due to some cluster or puck style designs, that can often lead to beams of focused light that create hotspots, shadowing and require the need for multiple light fixtures for full tank coverage and light diffusion.

Orphek has been offering panel style LED lighting solutions for the last 10 years, providing a highly diffused light source and delivering the perfect intensity and spectrum to the reef aquarium in the form of the Atlantik series.

Orphek introduced the OR bar reef aquarium LED range of products which have been designed to offer an alternative to T5 lighting and for 2020 Orphek will launched the new OR2 150 /120 /90 /60 LED bar system series.

Developed from the ground up, the OR2 series come with wider selection of chip LED technology and has improved from the previous OR model in terms of the heat sink, power output and spectrum that now is wider, coming in 4 different lengths.

The idea was to develop an affordable LED, offering a T5 – like coverage length of the tank, but has all the efficiency, spectrum choice and power associated with LED technology with the following benefits:

OR2 bar LEDs typically use 50% less power consumption than T5.
Unlike T5 bulbs, which need to be replaced very 6-12 months, LEDs require no maintenance.
There is no new acclimation period required for corals – there is with T5 replacement for new bulbs.
OR2 bar LEDs have an output of around 2 x that of a comparable T5 bulb – meaning less units are required to fully illuminate the aquarium.
OR2 heat sink is around 41C and the heat is dispersed upwards rather than heating the aquarium water.
Each OR2 bar has multiple LED color chips providing a balanced spectrum for each bar.
OR2 LEDs penetrate the water column giving better performance at depth, providing a shimmer effect to give the aquarium a sharper, colorful visual appearance.
OR2 bar LEDs come as standard in 2 spectrum choices with customized options available for special order.
Just 2 x OR2 bars, a combination of 1 x Reef Day Plus and 1 x Blue Plus will deliver PAR of ~400 at the surface and ~250 + mid aquarium mounted 20cm above the water level.
