This time I will be here for 6 weeks only, visiting seagrass meadows of Pulau Tikus (Pulau Seribu, in front of Java) and Derawan (Kalimantan) again. I am working together with Wawan Kiswara (the Indonesian seagrass expert from Jakarta) who is very helpful and has a never-ending hospitality surge. Together with his daughter Nina we had our first long fieldwork day in Pulau Tikus. In Pulau Tikus we could find mono-species meadows of Halodule uninervis like we have in Derawan Island, but the big difference is that here they are still ungrazed.

After 3 weeks we went back. Arriving in Jakarta from Derawan we left already the next day for the last fieldwork on Pulau Pari and Pulau Tikus. My planning was very tight, maybe a little bit to tight because Wawan and I already also worked for weeks without weekends and making long working days (7-22) every day but there is so much to do,! Based on the field station of LIPI on Pulau Pari (=stingray island without stingrays) we could reach Pulau Tikus in 30 minutes. I added some more pictures of the end of experiment on Pulau Tikus. The gaps in the ungrazed seagrass recolonized the sandy gaps (created 20 days ago by us) very fast. So the experiment was a success, now we compare it with the seagrass regrowth in gaps of in the grazed area of Derawan.

    Hi Marjolijn,
    I am the french tourist who was your sister in foot-pain in Derawan, because of a treacherous stingray… Remember? 🙁
    I hope you have recovered fine and nothing worse happened. I just discovered your blog today and I’m going to read it carefully the next days, to learn more about the turtles, the seagrass, and follow the progress of your researches (and beach cleaning).
    Take care!!!
    🙂

    @ Corinne: Hey Sister in stingray-pain!

    The stingray was not so kind to me. After you left I got a major infection, today, 2 weeks after the sting I still cannot walk and the wound is still inflammated, despite the good care Dokter Wita. All because the mantri (stand in for the docter that gave me the first care) put the unclean scissor 5cm deep inside my foot! Wawan finished all the fieldwork for me so the research is still going great.
    Nice that you found my weblog! I should update I more frequently but you now the internet situation on Derawan island 😉 In the next 2 weeks I will update it with new posts! I am also so happy to know your blog, it’s great, except sometimes I have to guess for the french translation 🙂
    What a great overview of how to travel to Derawan! AT the moment I’m back in Jakarta for some last visa things before going back home and where I can finally ask for a major foot-check-up!

    Keep on diving & posting such nice stories!

    Hey Marjolijn,

    Hoe gaat het met je voet? Is ie al weer een beetje geslonken? Ik vind het echt zo kut voor je dat je dit nu ook nog moet overkomen. Nou gelukkig ben je bijna weer thuis en kun je hem even goed laten nakijken. Ik hoop dat je snel weer helemaal kunt rond rennen…

    Wij hebben net onze vakantie geboekt (dit x wel heel erg last-minute) we gaan maandag naar Bali! Heb er echt super veel zin in! Lekker mijn werk bij PRA achter me laten en relaxen voordat ik met de nieuwe job @ UMCG begin. Als ik terug ben van vakantie moeten we snel afspreken hoor! Zie je eind aug/begin sep.

    Hee Marjolijn,

    Dat is grappig! Ik was aan het googlen naar ‘seagrass regrowth’ en de eerste link die ik krijg is jou website. Ik wou wat opzoeken omdat ik wat ideeen heb voor een eigen projectje en nu kom ik dus bij jou terrecht. Echt heel cool! Dit onderwerp wordt dus al gedaan, en zelfs heel dicht in de buurt …. haha! Ik ga zo maar eens even lezen wat jij er allemaal mee doet.

    Hoe is het verder? De tijd zit er volgens mij alweer bijna op toch?
    Nou, nog heel veel plezier daar, geniet ervan, ook van het warme weer. Hier is de sneeuwman weer geweest en vriest het nog steeds.

    Groetjes MOnique
