JBL Expedition South Seas I and II

JBL Expedition South Seas I and II

Feeding trials under water

Besides kitchen waste we had underwater feeding experiments on our agenda, as on every JBL expedition. Due to the extreme currents, only sites in areas with slight currents, such as the anchorage within the lagoons, were feasible.

At a depth of just a few metres, the fish were offered various food mixtures (prototypes for the planned JBL marine food) and their reactions were recorded. A freshwater food was used as a comparison food and it was clear that many of the reef inhabitants were reacting with significantly less enthusiasm to this food. The ingredients of freshwater food are designed for freshwater fish and not for marine life.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
